You get a Need admin approval dialog saying that the FlexNet Beacon needs permission to access resources in your organization that only an admin can grant.

Also include what kind of authentication service is used in your organization and what region and country the machine and Microsoft 365 tenant reside. Note that some regions (e.g., Germany) have separate login URLs as explained in
