I am new to Smartsheet but learning fast. We are starting a project to use Smartsheet for client onboarding to our software. I intend to create a client-facing dashboard but would like to restrict a user's access so they cannot click on the Home tab which they have no reason to view and is just a place for them to take a wrong turn and get lost. I even tested sharing the dashboard to an external email address and the Home tab is still there. Any ideas? Thanks
