Find a source
Use /catalog for known groups and /scan for groups visible to connected accounts. For a new topic, Zuvi expands your description into possible search phrases. A public link can be added directly.
After selection
The chat joins your source list. If no working account has joined it yet, access remains pending. /status tells you whether search is ready for selected sources.
Private groups
A closed group may need a valid invite, administrator approval or a captcha. The service owner handles those steps through the relevant account; customers see only connection status.
