How to make device on Wi-Fi hotspot discoverable to USB tethering connected PC?

My goal is to make the device (Quest 2) on 192.168.254.x (Wi-Fi hotspot) discoverable to my PC on 192.168.96.x (USB Tethering), because I want to set up ALVR and make my Quest 2 and my PC on different subnets talk to each other. Right now, I'm testing with **laptop - rooted phone with Termux - PC** configuration. I tried ip route add 192.168.254.13 via 192.168.96.20 command, where 192.168.254.13 is my Laptop with Ubuntu and 192.168.96.20 is my PC with Windows 11. My PC does not respond to pings from my laptop, but the laptop does ping the gateway which is 192.168.96.19, and is getting responses. I'm probably doing something wrong, but can't figure out what exactly. I don't have much network knowledge and I have a basic Linux understanding, so any answer/tutorial will be appreciated. I don't need any internet access when on Quest, but I would still want internet on my PC.
