Hi @Delfi_r, welcome to the community and to zrok (and OpenZiti)!
Generally speaking there's no way to share multiple services on one install. You can run one zrok share container for each service to expose.
Did you also find this other discourse post that covers the same topic?
There's also a feature request: Single Command, Multiple Share|Access · Issue #194 · openziti/zrok · GitHub to enable this sort of functionality on the roadmap.
