Go to the Teams tab in Teams Manager.
Find the team you want to edit under Active Teams.
Click on the three dots (⋯) in the right corner of the team.
Select 'Edit Metadata' from the options.
In the dialog box that appears, click on the 'Edit Metadata' button.
Modify the values in the metadata fields as needed.
Click 'Save' to update the metadata.
You'll see a confirmation message once the metadata has been successfully updated. Remember, these changes will also sync with SharePoint List if you have list synchronization set up.
