...     ...

• {token} is a long code, usually prefixed with xoxb-

Testing

Use this manifest to create an app:

display_information:
  name: tqdm
features:
  bot_user:
    display_name: tqdm
oauth_config:
  scopes:
    bot:
      - chat:write.public
      - chat:write

Note that the chat:write.public scope is only required to send messages to channels the app isn't member of.
