## Setup
|
|
|
|
Create a new telegram bot
|
|
|
|
1. Use BotFather to create a new bot
|
|
2. Use BotFather to disable its privacy mode for group chats
|
|
3. Use BotFather to add commands (that appear in the groupchat). Recommendation: `userlist - List native online users`
|
|
|
|
Create a telegram group
|
|
|
|
1. Manually create a group chat and add the bot to it
|
|
2. Convert group chat to supergroup
|
|
3. Grant bot to be an administrator (including ability to add more administrators)
|
|
4. Settings > "Who can add members" > Only administrators
|
|
5. Create an invite link
|
|
|
|
Handover to `nmdc-telegramfrontend`
|
|
|
|
1. Run this bot with no `-GroupChatID`, to learn the groupchat ID
|
|
2. Post a test message in the group chat, to discover the groupchat ID
|
|
3. Leave the group chat (long press on mobile, can't do it on desktop)
|
|
4. Run this bot with `-GroupChatID` for normal operation
|
|
|
|
## Usage
|
|
|
|
Chat with the bot to enter/leave the synchronised channel.
|
|
|
|
Sometimes the telegram invite links can take a few minutes to activate, especially if there has been unusual activity (e.g. frequent join/parts)
