Not able to create users / resource groups in Azure playgrounds

Hello I am currently working on the AZ 104 azure administrator course and trying to replicate what is being taught i.e creating users or resource groups in azure playground but i am not able to create any of that saying that i dont have the permissions. Do you know how I can be able to create these in azure playground and if not what is the purpose of the playground?
thanks

The playgrounds allow you to do a great deal, but there are actions that are problematic because they allow users to create resources that are costly and would prevent us from offering the playgrounds at all for that reason. So we block certain kinds of access. Anything that might allow you to create a user with some access rights we’re likely not to permit for that reason. Even Microsoft’s free accounts have similar kinds of restrictions, for that reason.

Hello @rob_kodekloud ,
While I understand the need to prevent excessive costs, it’s essential that the playground aligns with the practical learning experience for the course. If we can’t perform fundamental tasks like creating users or resource groups, the relevance of the playground to the AZ-104 certification becomes questionable.
