I have followed this guide but it doesnt work to reach 192.168.100.1 from clients which connect to the wireguard server. is there anything else to add to the routing to make it work?

I have successfully linked left (192.168.100.1) and right (192.168.8.1) routers through this howto. But when I connect from the phone (bottom) device to right wireguard server. I cant reach the left router (192.168.100.1)

I can access 192.168.100.1 from the 192.168.8.0 LAN, but I cant access 192.168.100.1 from the wireguard client through my phone.

For the phone I have added another Wireguard client config (10.0.0.3). the link between the routers use 10.0.0.2
