Hi - first of all thanks for this action/code.

I'm using it to...well, find a comment :) and I was trying to make the search case-insensitive.

In the regex, I've tried:

\^.*no-experiment.*$\gi << silently fails (no error, but doesn't find "no-experiment" or "no-experimenT")

(?i)^.*no-experiment.*$ << throws an error

The error from the second regex is:

Error: Invalid regular expression: /(?i)^.*no-experiment.*$/: Invalid group

So it seems that the regex start/end /.../ are being added when the regex is parsed, so I'm unable to add anything outside the regex start/end (no flags i.e. case insensitive).

Do you know of a way I can achieve above? Or I can also submit a PR to make the search for body-includes case insensitive if it wasn't intended to be case sensitive (is it?)
