Notify that files have been deleted from Google Drive

Hello! I am new to Make and could use some help. With my work, I am looking to watch/monitor files in a Shared Drive, and if a file is deleted then I want to receive a message in Slack in my drive-trash-monitoring channel.

I found this post, and one of the users says this:

Could someone please walk me through a scenario that would accomplish this?

Thank you so much!!
