As suggested on discord. This may not be the final solution, but it's working at the moment.
Get a cookie of the logged website: Apparently for this website the Key is PHPSESSID.
Put it into the request headers and you should be able to access the protected page.
This is worked for me. "xxxxxxxxxxxxxxx" should be the value of the cookie in your browser.
For testing I wrote this code above the line 38 where the "Referer" is set.
