As I understand, not that many use the wiki tab in Teams. Could be that I’m wrong. Anyway, her is a script that removes the Wiki tab from every channel in every team in your tenant.

Which API permissions do I have to set?
I always get
Invoke-RestMethod : {
“error”: {
“code”: “Authorization_RequestDenied”,
“message”: “Insufficient privileges to complete the operation.”,

I already have this permission, but it still does not work.
