One PowerBI Embedded app and multiple users

Hi,
Is there any clear way where I can add another user who can generate token or it need to be separate app?
As an example I have one PowerBI Embedded Native app in azure AD with assigned username but I want to assign another user who can generate tokens also (in case where I want to split data per tenant on the BI side). So far only my account works even if I add second account as an owner of this application.
