Remove the post-gift sharing block

In GiveCampus giving forms, available controls depend on your permissions and the interface used by your institution.

The standard newer donation confirmation displays social-sharing links. A separate prelaunch offer flow can suppress sharing, but that does not mean a self-service hide-sharing control for this ordinary form. Ask support to review the exact form/template for an approved presentation change; changing the thank-you text alone does not remove the share block.
