Hi,
For this you will need to assign RBAC role to the user, by default it is not enabled and hence you are seeing this error, so either you can delegate existing roles or create a custom role as per your requirement - https://learn.microsoft.com/en-us/azure/active-directory/roles/delegate-app-roles
Azure AD RBAC - https://learn.microsoft.com/en-us/azure/role-based-access-control/role-assignments-portal
