How do I delete a review comment made on pull request?

How do I delete a comment I made on a pull request? I commented a review twice on the same pull request by accident.

Is it possible to delete this comment? See picture for reference. I clicked on edit, and removed all content, but this creates an error. Editing the comment also doesn’t bring up any “delete” option.

Any help is appreciated.

Currently you can’t. The only way would be to report it to GitHub, but I wouldn’t suggest that for that simple case.
