Extensions Menu Not Showing

I have installed plugin called cleanup, but after installing it, The extensions menu not visible beside window menu. What to do??I have done apply changes in extensions manager.

CleanUp requires this extension as well:


Install TT_Lib², then close SketchUp, and open it again. CleanUp needs TT_Lib² to be initialized first, which means adding TT_Lib² second isn’t enough. Either add TT_Lib² first, then CleanUp, or close and reopen SketchUp after doing both installs.
