You also add the -R parameter:
ssh -R SERVER_IP:443:HOME_PROXY_IP:HOME_PROXY_PORT user@SERVER_IP
https://linuxize.com/post/how-to-setup-ssh-tunneling/ (you want the "remote port forwarding"). ssh -R, -L and -D options are magical, more people should learn about them.
You may also need to open access to port 443 on the VPS. How you do that depends on the VPS service, check their documentation.
