Browser integrity check -Firewall event

Hi, I need to make a rule for page bnr.php on domain.
The page contains 2 currency values which are read from a standalone desktop application(A billing software).

If I disabled Cloudflare for domain, the currency values from page bnr.php can be read as expected.

Here is the firewall event when I try to read from page.

I have a single rule.

What page rule or other security setting should I do for reading from the page?

Thank you,
