Macos warp beta app question

Just got the beta invite for the macos warp beta, running fine but a bit unclear about how the app is changing my settings: when using only the dns in the app (see below) I do not see any vpn settings in system preferences/network, and the dns settings is also not changed, but somehow shows I am using the dns-over-tls…how can the app change my dns behavior? I did see a “utun2” in my routing tables with netstat -nr so does it work that way? i.e. sending traffic to the local daemon and re-routing dns querys? would feel more comfortable if I know how things work on my machine… thanks!
