Authenticating Google account outside of MAKE


I am building an automation that will send a google calendar invite. In the process you have to authenticate a google account to send from it inside of the Google Calendar node in the scenario. I do not want each user to log into make to process the authorization and I am wondering if there is anyway to provide some sort of workflow to get users to authenticate their google accounts outside of logging into MAKE so they can use the scenario I am building?
