Authenticating private github repo for building wave containers

Hi!
I’m enjoying being able to use Wave to build container images on the fly by just putting a Dockerfile in the module folder. However, now I’m in a position where I need to build a container with code I’ve written that’s stored in a private github repository. What’s the best way forward, using the seqera.io platform? Somehow sharing a PAT? I don’t really want to bother with a container repository but if that’s the only way forward then I’ll do that!
