I do not understand how to delete messages via RTM bot objects...

Slack API supports deleting messages via bot users, as far as I understand with the “as_user=true” argument in api call. In this case it is a RTM API call, not a Web API call.

It looks like this is also possible in the node-slack-sdk, but I am not able to reverse engineer the necessary code…

Something like:

var RTM_EVENTS = require('@slack/client').RTM_EVENTS;

rtm.on(RTM_EVENTS.MESSAGE, function handleRtmMessage(message) {
   rtm.chat.delete("<TIMESTAMP>", "<CHANNEL-ID>", "as_user=true");

This method “chat.delete” is available for the Web API in this wrapper, but only a bot user is allowed to delete on behalf of another user.

The plan is to create a read only channel e.g. through deleting all messages from others than the channel owner…

Thanks for any hints in advance!
