In our custom deployment, I’ve set up a regular user under a new Realm.
When I login with this user to the correct realm I get access only to the Edit Account page. No links or buttons to navigate to other parts of the Manager and if I try to change the url to /auth/realms/test it shows me the attached page
You need to create it
When you create the openremote instance you have a Master realm and your master admin account.
Master admin account can see all realms and work on them
Users are related to the realm you are working in, so you first create a new realm
