AMAZING Update to Power Platform Licenses - August 2023

Great video!! I have a question though; If I create a desktop flow and I want to charge 10 different users for using my flow unattended on 10 different private Virtual Machines.

Does that mean I'm gonna have to pay $150 × 10 users = $1500 per month for the unattended license??

If an external user (supplier) is authenticated from the local contacts Dataverse table, that has been pre-populated with their account information, and once authenticated the Power Page shows a Power App embedded in an Iframe, that shows their supplier data that is stored in Dataverse, What licenses are needed?
