Can I undo "share as template"?

I wanted to share so someone in my department could use it-but I didn't want to make it public. Can I delete that somehow?

Yes, it is possible to delete a shared template. Please follow this guide: How-to-Unshare-or-Edit-a-Shared-Template.

You may also share the form template URL here so that we can delete it for you.

Hope that helps. Thank you.
