Slack + confluence cloud integration: Deleting a Slack post from Confluence Cloud

[CJ Avande]

How do you delete a Slack post from Confluence Cloud? 

 We set up an integration so that every time a new page is created, a post is sent to a specific Slack channel. 

Here is the post: https://share.getcloudapp.com/YEuOWbwP#

One page was published in error, but there is no option to delete the post. How do I delete this?! 

Thanks for help!

Ignore the question: I found out only Slack admins are able to delete. Thanks!
