Power BI Node and conditional access - does it come with anything extra?

We done a simple proof of concept that shows we can use AAD P1 conditional access to require a user to sign into Power BI every 12 hours.

Does a Power BI node come with any AAD P1 licences, or EMS-E1/2/3 etc licences that we can use? Or is it consuming existing AAD P1 licences we have?

Basically is our Power BI subscription bringing anything to the party or just eating our food? ;)

Thanks
