How to use my hysteria2 config as system proxy on sing box Android app (non rooted phone) ?

Everything is pretty much in the title.
When I add my sn:// config to the sing box app and run the service, nothing happens, no VPN request.

This link seem to say that I can use system level via `tun.platform.http_proxy, but I do not know what is this exactly and haven’t yet found a way to use my config as system level proxy.

Best regards.
