Slack/Mattermost: notify only on success if last_build failed

Drone Support

Hi there :slight_smile:

Is it possible with the drone-slack plugin to send notifications every time a build fails AND just the message for the first successful build afterwards - no more success messages after this one.

I am using the open-source/selfhosted slack alternative mattermost.

Something like:
failure: build #123 failed
failure: build #123 failed
success: build #123 is fixed!

Or is there some other plugin/solution to achieve this?
