You should know that the following warning message is displayed in the activity logs for all the team creations:
Please do not take this message into account.
It appears because of a new Powell Governance tab that Powell Governance application tries to add automatically into the general channel of the new teams. The tab allow owners and members to see the detail of the team governance information.
Adding this tab automatically requires a new permission for the application that is not included into the actual consent. The new permission will be added to the delegated and advanced consent in the next release.
If you want to benefit from this tab right now, you can still add the tab manually into the reference team of your template and then resync the template. The tab will be added normally without any warning message.
