Hello @ALEXTOR ,
I had the same issue and developed a workaround.
Since the Team is actually created, it is no problem if you set a 2 minute timeout for "create a team" action.
If your flow concludes after that action, just create a terminate action, set the run after of the terminate action to "is successful" and "has timed out".
If you need to find out the Group ID for the Team, you can use the "List Teams" action in combination with "Filter Array" and get the right Team ID in a compose.
If you need a more detailed description, please let me know.
