Is there a list of the names for each inbuilt ribbon tab that can be used with insertBeforeMso and insertAfterMso in the Custom UI Editor? I have searched high and low with no success. Many can be worked out by guessing, but I don't seem to be able to identify the Help tab.

Apologies if this answer is already here somewhere, but I have spent a lot of time looking on this site and elsewhere with no success!
