Generic Login from Trusted Site

I have built a private app that will has two types of users: administrators (who will log in to Bubble directly to do their work) and everyone else (who will have view-only access). Ideally, “everyone else” would access the app by clicking on a link in SharePoint 365 which would log them into the Bubble app as a viewer. Is there some way to set up an automatic, generic log in to the Bubble app from SharePoint 365?
