Hello @Hanni80
Are you the account owner and have you activated the professional tools? I am a one woman band so don't have a co-host or a team set up but there is additional information on Airbnb on what the two can do and their differences.
I can't find any information on how to set up payments for team members other than through a contract. Here is a link that might help but there is additional information available by clicking on the key words:

Sorry that I couldn't be more helpful but hopefully another host will chime in,
All the best
