Thanks. Will update the script

Actually, the script looks for ChannelMessage.ReadWrite, which is one of the scope permissions listed. Maybe your session didn't have this permission?

it did have this permission as you can see above in the script output it lists I have Scopes on the request 'APIConnectors.Read.All, AuditLog.Read.All, ChannelMessage.ReadWrite, ChannelSettings.Read.All,

I admit it is weird as you would think that would give Read as well, but as soon as I added ChannelMessage.Read.All to the scope the error fixes itself

Another Graph mystery...
