Hi @Anonymous
what corresponding requirements do I need or do I need to purchase a license?
Yes, you need a valid Power Apps license.
Meanwhile, to embed an app into Teams, you also need an existing app created using Power Apps.
For more details about how to embed the application into Teams, you could refer to this part of artcile's steps.
