Since I've created my Environment with Databes not in open mode. I now need to add users to the environment and assign them to the security role which has access to my custom entities. Before yesterday I use to go to the Environment and Add users on the Security tab (following this link https://docs.microsoft.com/en-gb/powerapps/administrator/database-security). Since Add User is no longer available on Security Tab I can't find any way to add users to my environment anymore. Can you please advice?
