Forward traffic from wireless interface to other device on simulated network

I want to use services like Barrier on my university network but LAN is prohibited on it. To fix this, I directly connected an ethernet cable from my laptop to the PC I wanted to control and followed the steps shown in https://askubuntu.com/a/1276657 . It works, but now I would like to route my laptop's wifi internet traffic to my PC. Is there any way to do this using NetworkManager and/or bridges and/or NAT? It does not matter to me if the two computers share a local IP address.
