I am trying to do automation to get an email notification when an issue's comment has been edited. I would like to show the previous comment and the newly edited comment.
I looked around and saw that this trigger has not been implemented yet but I used the multiple event trigger and saw that Issue Comment Edited is available. Is this any different?

I have been playing with it and it looks like it's working well. The only other issue is that I am unable to show the comment before it was edited. I tried using this:
CHANGE FROM:
{{fieldChange.field}}: {{fieldChange.fromString}}
TO:
{{fieldChange.field}}: {{fieldChange.toString}}
Unfortunately this does not work. I am using a JIRA Server.
