Firebase with Discourse server

[Adam Beers]

I'm trying to use Firebase with a Discourse server and I can't quite figure out the settings.  Has anyone tried this config before?  I was to use Firebase for the authentication and have the Discourse host the forum.  I'm trying to use SSO, but maybe it's not possible.  I found in the Discourse settings a sso_url, but I don't know what to put there.

Thanks in advance!!
