Brave browser doesn't support SOCKS5 proxy authentication

I installed SwitchyOmega a few days ago and have been testing it with some proxies. When I try to set it for SOCKS5, it warns me that my browser doesn’t support SOCKS5 authentication. Indeed, when I try it, I get proxy error.

I had found some threads complaining about it, all of them with no reply and closed due to inactivity.

Is this a chromium limitation, or Brave fault? I know that per-tab proxy isn’t possible because extension API doesn’t support that, but what about SOCKS5 proxy?
