Extendig comments (activity /tab-panel)

Hello guys,

I am looking for way to add a button or better a custom component to every comment in an issue.
I don’t find any suitable atlassian connect modules for extending the comment section in the new, neither the old, issue view.

Am I missing an important point to do so?
Could you elaborate on how I can implement this use case?

Thank you all.

@mwa, in the old issue view, Web Items can be added to the list of issue comment actions by using the location issue.comment.actions. I don’t know if that works in the new issue view.
