How export RDM config ? (.cfg)

Hi !

First, I want to give you a gift :

tasks:
  - name: Ensure the required NuGet package provider ve$srsion is installed
    ansible.windows.win_shell: Find-PackageProvider -Name Nuget -ForceBootstrap -IncludeDependencies -Force
  - win_chocolatey:
      name: 
      - sql-server-express
      - rdm
    become: true
    become_method: runas
    become_user: "{{ ansible_user }}"
  - community.windows.win_psmodule:
      name: RemoteDesktopManager
      state: latest
  - name: Configure SQL
    ansible.windows.win_shell: |
      Invoke-Sqlcmd -ServerInstance "{{ db_instance }}" -Database Master -Query "sp_configure 'Remote access', 1 ; reconfigure"
      $s = new-object('Microsoft.SqlServer.Management.Smo.Server') '{{ db_instance }}'
      $s.Settings.LoginMode = [Microsoft.SqlServer.Management.SMO.ServerLoginMode]::Mixed
      $s.Alter()
      Restart-Service -Name 'MSSQL$SQLEXPRESS'
      Invoke-Sqlcmd -ServerInstance "{{ db_instance }}" -Database Master -Query "CREATE LOGIN [{{ rdm_dblogin }}] WITH PASSWORD = '{{ rdm_dbpass }}'"
      Invoke-Sqlcmd -ServerInstance "{{ db_instance }}" -Database Master -Query "CREATE USER [{{ rdm_dblogin }}] FOR LOGIN [{{ rdm_dblogin }}] WITH DEFAULT_SCHEMA=[dbo]"
      Invoke-Sqlcmd -ServerInstance "{{ db_instance }}" -Database Master -Query "GRANT ALTER ANY USER TO [{{ rdm_dblogin }}] WITH GRANT OPTION AS [dbo];"
      Invoke-Sqlcmd -ServerInstance "{{ db_instance }}" -Database Master -Query "GRANT CONNECT TO [{{ rdm_dblogin }}] AS [dbo];"
      Invoke-Sqlcmd -ServerInstance "{{ db_instance }}" -Database Master -Query "GRANT CREATE ANY DATABASE TO [{{ rdm_dblogin }}]"
  - name: Configure RDM
    ansible.windows.win_shell: |
      $cd = ConvertTo-SecureString "{{ rdm_dbpass }}" -AsPlainText -Force
      $reg = Get-RDMRegistrationInfo
      $reg.Name = '{{ rdm_regname }}'
      $reg.Email = '{{ rdm_regmail }}'
      $reg.Serial = '{{ rdm_regserial }}'
      Set-RDMRegistrationInfo $reg
      $d = New-RDMDataSource -Database "RemoteDesktopManager" -Name "{{ rdm_dsname }}"  -SQLServer -Password $cd -Server "{{ db_instance }}"  -Username {{ rdm_dblogin }} 
      Invoke-RDMCreateDataSourceDatabase $d
      Set-RDMDataSource $d
      Set-RDMCurrentDataSource $d
      Get-RDMDataSource | Where-Object -FilterScript {$_.Name -ne "{{ rdm_dsname }}"} | Remove-RDMDataSource
      Invoke-Sqlcmd -ServerInstance "{{ db_instance }}" -Database Master -Query "REVOKE CREATE ANY DATABASE TO [{{ rdm_dblogin }}]"
      $d = Get-RDMDataSource
      $u = New-RDMUser -Administrator -Login "{{ rdm_adminuser }}" -AuthenticationType Builtin -Email "{{ rdm_adminmail }}" -Password $cd 
      $u.FirstName = "{{ rdm_adminfname }}"
      $u.LastName = "{{ rdm_adminlname }}"
      $u.UserInfo.UserAccount.UserMustChangePasswordAtNextLogon = $True
      set-rdmUser $u
      Set-RDMDatasourceProperty -DataSource $d -Property UseDBLogin -Value $True
      Set-RDMDatasourceProperty -DataSource $d -Property LoginMode -Value "Custom"
      Set-RDMDatasourceProperty -DataSource $d -Property DBLoginUserName -Value "{{ rdm_dblogin }}"
      Set-RDMDatasourceProperty -DataSource $d -Property DBLoginPassword -Value "{{ rdm_dbpass }}"
      Set-RDMDatasourceProperty -DataSource $d -Property UserNameEditable -Value $True
      Set-RDMDatasourceProperty -DataSource $d -Property User -Value "%USERNAME%"
      Set-RDMDatasourceProperty -DataSource $d -Property Password -Value ""
      Set-RDMDataSource $d
      Set-RDMCurrentDataSource $d

A full Ansible playbook to :

• Install sql + RDM
• Configure SQL access
• Configure RDM for SQL datasource with custom login (because Integrated Security is not really secure)

But. Something is missing. I need to export a .cfg as the default.cfg. (multi users support)
In the UI, it's in "Options -> Export Options -> Export". But I don't find how to do this in Powershell
And, how can I hide the registration serial to no-Administrator User ? (in UI + Powershell)

Thanks you !
