How to extract JSON from response body in Gatling

Question

I am using Gatling and want to extract JSON from the response body and then use jsonPath on that. To be clear the response is something like this:

<html>
<!-- usual stuff here -->

<script>
/* JSON I WANT TO EXTRACT */
{
var1:'val1',
var2:'val2'
}
</script>

<!-- rest of HTML content -->

</html>

I am able to get the JSON using regex:

val chain = exec(http("Homepage")
    .get("/")
      .check(regex("""myJsonRegex""").find(1).saveAs("responseJSON"))

That's not the actual regex, but not the point, the regex works and I can isolate the JSON, but I would really like to use jsonPath on that saved "responseJSON", not sure how to do that. I can probably just do the whole thing with regex, but it would be much cleaner with jsonPath.

You could use circe or more specifically circe-optics for that. The documentation has a few decent examples.
