Remove "Share Page Button"

The ability to remove the "Share Page Button".

Right now, when a user chooses to open the supademo in a new tab, they're brought to the Share page and the user can see the Share Page button that's customizable.

For our use case, there isn't a need to have that button, so we're having a hard time figuring out where to link it to. It'd be great to have the option to unselect having that button there.
