Adobe Acrobat for Microsoft Teams

Hi, we would like to implement Adobe Acrobat for Microsoft Teams. But it is unclear for us what are the prerequisities for doing so and have full functionalities of this extension. We would like to enable our employees to open and edit PDF files directly in Teams. Does every user needs adobe account and what plan / license? How is it with signing in to the adobe account within the Teams, is it only single action in the beggining or do users need to sign in every time they want to work with PDFs within Teams, or is there any possibility of SSO?

We are looking for the absolute neccesary minimum requirements to meet, to enable this functionality for our employees within the Teams.

Is there any more detailed source of information except of this website?
