Kollaboratives Arbeiten Adobe Acrobat

Thank you, but that's not what I meant by collaborative working. The point is that several people can work in the document at the same time without the document being saved as a copy.
There is Adobe Acrobat for Microsoft Teams. But we would like to know whether these collaboration functions are also possible via Adobe Acrobat without a license for Microsoft Teams.

You can do a collaborative review, using comments, but you can't collaboratively edit the static contents of the file, if that's what you mean. PDF files were not built to be edited in this way.
