Multiline regex not working in heartbeat

Hi, I have a working RCE2 regex against below response but when applied on the heartbeat it doesn't pass the positive match. Goal is to assess if there are at east 11 countries returned (actually 200 but than tested string will be too long for this post), Any idea why the regex isn't working in heartbeat? Am I quoting it wrong or...?

heartbeat version 8.17.3

Heartbeat monitor.d yml:

- type: http
  name: 'name'
  id: 'id'
  schedule: '@every 5m'
  hosts: ["url"]
  ipv4: true
  ipv6: false
  mode: any
  check.response:
    status: [200]
    body: '`(?:<Country>.*?){10}(</Country>)`msg'

Test string:

Hi @jweeda , welcome to our community!

Have you tried?

'(?:<Country>.*?</Country>){11,}'

Thanks for your reply. It turns out that the output in the browser returns xml due to the Accept header (text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,/;q=0.8,application/signed-exchange;v=b3;q=0.7). The heartbeat call didn't contain this header and therefore returned differently formatted output hence the xml based regex did not work.

below setting in the monitor config helped identifying above:
response.include_body: on_error
