Rocketchat 5.x / Jitsi Integration (Marketplace app) in an offline RC instance

Description

Starting with version 5.0 the default Jitsi Integration has been moved to an app in the Marketplace. Is it still possible to use the Marketplace in an offline installation somehow? Trying to get Jitsi working again in RC >=5.0 without the RC Server having internet access. Sideloading apps seems not an option anymore, am I missing something?

TLDR: howto get Jitsi Integration (marketplace app) in an offline (no internet access) Rocketchat 5.x Installation.

never mind, free tools like Jitsi.App are on github and can be build / deployed in offline instances just fine with the rc-apps tool
