Access by Outside Users

Hello! I know there are view/edit accessibility options that can be set for outside users when sharing a sheet. However, we want to be able to have outside users approve/deny requests automatically sent through smartsheet forms/requests but not have access to view the sheet itself. Is this possible? When an auto email gets sent from smartsheet a link is included to the sheet.. can this be removed (Screen shot example below)? Thank you in advance for any help!
