I got the answer
When I log in as a guest user, I am unable to access the web client. I tried giving my test user the Owner permission for the resource group, but I still can't see anything and the system shows an error message
"It looks like your system administrator hasn’t set up any resources for <my email> yet. Please choose a different account or try again. If you believe you have received this message in error, please contact your system administrator.".

I don't know what to do. Can you please give me some advice?
