CircleCI SaaS and Github Enterprise?

Is it possible to use CircleCI SaaS (not CircleCI Enterprise) with Github Enterprise?


I’m also interested. It appears that in order to connect to a Github Enterprise instance, one needs to use the ‘behind your firewall’ on-prem version of circle CI. Ive downloaded the trial and have a support ticket open to confirm

Join over 300,000 developers already using CircleCI’s first-class integration with GitHub and GitHub Enterprise to enable build and test automation.

But I cannot find how to collaborate each other.
