List github issue revisions - octokit

Question

I'm developing a probot application to prevent disclosure of sensitive information on github issues.

When I edit out the sensitive information from the github-issue, the information can still be viewed on the post's edit history (revision history) where you can then manually delete them from the UI, as shown: Github-issues-revision-history and deletion

I've been using https://octokit.github.io/rest.js/v18 but there doesn't seem to be a clear endpoint to access said revisions.

Tried various approaches such as

var promise=context.github.issues.listEvents({owner:"james", repo:"test-repo", issue_number:56})
   promise.then((value) => {
  console.log(value);
})

but I can't seem to be able to find where those revisions are saved. Where exactly are those post revisions saved so I can delete them using my probot application?
