Change DNS servers from the networks KCM?

Help
1

There is an “other dns servers” field, but I’m just wondering what that means?
Because for me adding something there doesn’t do anyting and it’s still needed to edit resolv.conf.

For me, it works as expected:

$ nmcli dev show | grep 'IP4.DNS'
IP4.DNS[1]:                             1.0.0.1
IP4.DNS[2]:                             1.1.1.1
IP4.DNS[3]:                             8.8.8.8
IP4.DNS[4]:                             xx.xx.xx.92

and

$ resolvectl status

<snipped  for brevity>

Link 5 (enx1682ed4cf289)
    Current Scopes: DNS
         Protocols: +DefaultRoute -LLMNR -mDNS -DNSOverTLS DNSSEC=no/unsupported
Current DNS Server: 8.8.8.8
       DNS Servers: 1.0.0.1 1.1.1.1 8.8.8.8 xx.xx.xx.92

The last one is being set by Tailscale, and does not show in the GUI

My resolve.conf only shows the local 127.0.0.53 address, which iirc is expected.
