Beginner Here. Need help with an LFI/RFI vuln.

So i was on the academy the other day and was about to finish a module about File inclusions. After completing all the basic challenges I got stuck at the final assessment.

The website is related to a shipping company called “Inlane Freight”
Has a lot of templates and I have tried a lot of things but nothing seems to work.
I have no other way of showing the page to you without spawning the page first.

Help in any form is appreciated.
Please and Thanks
