Image Management

I am trying to add custom icons to website entries. When I click on Custom I see the following.


The above picture leads me to needing to use the Image Management feature. following the documentation from https://docs.devolutions.net/rdm/commands/administration/images/ in my ribbon under Administration, there should be a section called Configuration and Security. In this section there should be a button to click for Image Management. Problem is, there is no Image Management button, only Vault settings.

I've looked at the release notes by doing a control + F for image management and I don't see it as being a deprecated or removed feature. Am I missing something?
