[Python] Proxies with PyPartpicker (requests_html)...not being utilised?

I've just begun building a database updater that takes parts from PCPartPicker using PyPartPicker and uploads them to a supabase database. I've setup async functionality, but I'm having trouble with rate limits. As a result, I'm trying to implement proxy rotation to stop my requests being blocked.

Through some logging, I can see that the proxies are being cycled properly, but no matter what I can't see any proxy usage in my proxy dashboard. Not only that, it logs about 8 parts and then gets stuck on a Browser Listening: info msg, which is exactly what happens without using proxies. They're definitely not used for the requests, even though I've set it up exactly as the PyPartPicker GitHub and PIP documentation instructs. Anyone have any ideas as to how to actually see what ip is being utilized for the connection? My only though is that maybe the proxys MUST be socks5? But it looks like they are. I'm using a Webshare.io free plan. Or if I'm doing something wrong? Any help would be appreciated
