Using the same method as suggested above, can anyone please help by telling me what is the id, idMso of the "Power Pivot" tab?

I am trying to make the "Power Pivot" menu item invisible, but can't find the ID

This works for hiding the Data tab:
idMso="TabData", visible="false
This doesn't work for hiding the Power Pivot tab:
idMso="TabPower Pivot", visible="false
Thanks!
