Radicale on ZimaOS/CasaOS

Hi there!
I’m new to Zima/Casa and tried to get a docker-image of Radicale running (lightweight CalDAV/CardDAV-server) . It works, but I can’t get Radicales encrypted usermanagement running and SSL/HTTPS-connections from mobile/away won’t work yet in my testing setup. So it’s still unsecure for production.
Is there a chance to get it into the BigBearStore? I’m willing to help with testing, if this is an option.
Thank you!
