Not possible to add a team in the new Projects (Beta)

Hello together,

I saw the following information in the documentation:

You can also add teams, and individual organization members, as collaborators. For more information, see “About teams.”

But I tested this and for me it’s not working to add a team in the new project feature.

Maybe someone can give me a hint, how this is working or this is at the moment not possible for the new project feature?

Best regards,
