RDP entry - how to configure Devolutions Gateway

Hi Team,

Currently trialing DVLS and RDM Enterprise. In DVLS, I've successfully installed and configured a (remote) Devolutions Gateway instance which is testing as healthy.

Next, I created an RDP session in the Vault (using Web) and wanted to configure it to use the Devolutions Gateway. I found no settings for this, so I figured I had to configure this in RDM.

Installed RDM and configured it to use DVLS as the datasource. When configuring VPN/SSH/Gateway for the session entry, I choose 'Always Connect' and set the type to 'Existing' > 'Gateway'. On the Settings tab, I should be able to choose a Gateway but the gateway doesn't show up in the list. Even when I click on the button next to the list (with the three dots), it doesn't come up in the list. See screenshots below.

What am I doing wrong?

Thanks in advance for the help!
