Connect to Discourse Hub?

I’m hoping to move Discourse notifications into their own app rather than receiving them mixed in with email notifications so I just tried to connect in the official Discourse Hub app but it doesn’t seem to play nicely with SSO.

I’m guessing it’s just a limitation of their app (I also couldn’t connect another Discourse that I sign into with GitHub) but has anyone successfully managed to sign in? Or have another solution to moving discourse notifications out of email?

P.S. I chose this category because it’s where the original post about Help Center was posted…
