In order to use RTM, user needs to create a bot user? 2. I was able to user both `bot` and `user` types token with FetchSlack processor. However, while `bot` type api token works, I couldn't use `user` type token with this CS, I got following error. Only bot type token can be used here? ``` java.lang.IllegalStateException: Couldn't fetch RTM API WebSocket endpoint. Ensure the apiToken value. ``` 3. In order to receive messages in a channel, the bot app needs to be added to the channel. Is this correct? 4. What api token scopes are expected to be enabled? I think it'd be super user friendly if we document these things. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
