You cannot directly delete the run, but you can finish it.
When you click on the run in the overview in my screenshot, the detail page for this run will open and at the top right, you can click on “Go to channel” and you will be brought to the channel the playbook run is tied to.
Once you’re in the channel, you will see the run details in the rightmost column. If you cannot see the column, click the marked icon in my screenshot to toggle the run details.
Scroll down to the bottom and click on “Finish run” to complete it and muzzle the playbooks bot.
