That proxy is great, thanks for sharing! Most annoying thing about Medium pages is the multi-second waiting period while the page is loading. (On Chrome on a M1 Pro, mind.)
You can install an extensions called libredirect that would auto redirect, Medium, YouTube, Twitter and many others to private proxies.
Its not available on the chrome store because of manifest V2, there is privacy redirect but its abandoned and doesn't support scribe.
