🌎 Workers Browser Rendering Puppeteer Geolocation

I've created and deployed a Cloudflare Worker that uses Browser Rendering and Puppeteer to crawl a website.
My issue is that the website content is based on the IP location of the Cloudflare Server location, and not the user making the call.

There is no way of adding a query parameter to the actual url to adjust the locale (gl/hl).

I've tried to solve this on the Puppeteer level, by implementing various techniques from here, including setGeoLocation: https://zirkelc.dev/posts/puppeteer-language-experiment

Despite making all the changes to the Puppeteer environment, the browser still manages to capture the location of the actual Cloudflare Server location. When visiting https://ipwho.is/, I always get the incorrect data back.

How do I go about to solve this? Are proxies the only way forward? Where in the stack can I approach this issue successfully?
This is the current states of my attempts so far:
