Suggestion: display feedback when a message is deleted through s/!!/ #590
Description
When using s/!!/ it deletes the last message sent on the channel.
But then we never really know if this worked as expected.
It would be nice to extract the API call response details and write on the channel something like when someone else deletes a message, for our own deleted message.
I'm not sure what's the API sending exactly as a reply, but reprinting the deleted message itself would be reassuring!
Thank you!
