How to make NanoBot listen to all Telegram group messages, but only respond to the admin?

[BaGRoS]

Hi everyone,

I’m trying to build a maintenance workflow with NanoBot on Telegram, and I’d like to ask for the best architectural approach.

What I want to achieve

I have a Telegram maintenance group with:
• me as the owner/admin
• engineers (for example Mohammed and Richard)
• possibly other participants

What I want is:

1. NanoBot should listen to all messages in the group

   • so it can observe the conversation
   • detect status updates from engineers
   • notice when somebody says a job is done, in progress, or blocked

2. But NanoBot should only treat my messages as actual commands/instructions

   • I want the bot to respond to me
   • I do not want it to start chatting with everyone in the group
   • ideally, other users’ messages should be treated as signals/events, not as prompts requiring a conversational reply

3. Optional behavior

   • if an engineer says something like:
     • “done”
     • “fixed”
     • “lamp repaired”
     • “still working on it”
     • “blocked, no spare parts”
   • the bot should be able to:
     • update task status
     • optionally confirm completion
     • or silently update a pinned task list

4. Reminder logic

   • if a task stays open too long, the bot should remind the assigned engineer politely

The problem I found

From what I understand, Telegram currently has:
• groupPolicy: "mention" or "open"
• allowFrom

But allowFrom seems to work at sender level, not as:
• “read everyone”
• “only obey admin”
• “treat engineers as status-only users”

So if I keep allowFrom restricted to myself, the bot may not process engineers’ messages at all.

If I open it up to engineers too, then I worry the bot may start treating their messages as normal prompts instead of just maintenance status updates.

My ideal behavior

I’m looking for something like this:

• Read all group messages
• Respond conversationally only to admin/owner
• Use engineers’ messages only for workflow/task state
• Ignore everyone else silently
• Optionally maintain a pinned maintenance task list in the group

In other words:
• admin → can create/manage tasks
• engineer → can update status / mark done
• others → ignored silently

My question

What is the cleanest way to implement this in NanoBot?

Would you recommend:

1. extending Telegram channel behavior,
2. using groupPolicy = open plus custom filtering,
3. adding role-aware logic in a skill,
4. or introducing a new concept like:
   • read permissions
   • command permissions
   • silent observers / status-only users

Bonus question

Would it make sense to support a workflow like this natively?

Example:
• bot listens to all messages in one Telegram group
• owner assigns tasks
• engineers report progress in natural language
• bot updates a pinned message with open tasks
• bot sends reminders after 24h if needed

I’d really appreciate any advice on the best pattern here.

Thanks in advance.
