Authenticate one Bubble user with another Bubble user?

Does anyone know if it’s possible for one bubble account to provide auth to another bubble account?For example, lets say I had Bubbleapp.com that had a user then there was usefulbubblefeature.com had a dashboard that would be really useful to Bubbleapps.com’s users. Could Bubbleapp.com authenticate a usefulbubblefeature.com user as native so the user of Bubbleapp.com clicked /dashboard and was directed to usefulbubblefeature.com without logging in?

If they are two bubble apps you can setup the first one to be your “SSO” into the second one. This is done in the Settings / API / 3rd Party OAuth / SAML Access.
