I have an app, and I can use it no problem. What is the best way to let someone else use my app? I work with just one other guy.
I've been looking at Azure AD as this looks like the right way to go about things? Someone else mentioned creating a Dataverse database but I couldn't get very far with that.
With Azure AD, the 'Create user' option is greyed out. Is this because I need to change my license?

I will try the 'invite user' and see how I get on.
