Choose a source
Open the bot catalog, search by topic or add a public link. For your own group, you can add the bot with permission to see messages. Avoid unrelated chats that add noise.
Wait for access
After selection, /status says whether search is ready, still connecting or temporarily delayed. A private group may need a valid invite, approval or a captcha in a working account.
Verify the result
Once the status is working, try a suitable message in a test group you can access or wait for a normal post. An empty feed may simply mean no relevant new requests appeared.
Open the original
A message link and a group invite serve different purposes. If Telegram says you are not a member, join with an available invitation; a private post cannot be opened by its link alone.
Try it with your groups
Open Zuvi, choose an accessible source and test the rule on a real example before monitoring starts.
