for your case, people are not notified for this edit from external integration, right ?
just a thought, for your case, since you have a process that edits the post, is that done in another server ? if so, you could add some logic there, send a personal message (PM) the participants of that topic using discourse API.
I checked the API, the function to add an entry to notification is not exposed tho… but could do PM instead.
