Is there any indication in logs that openconnect is getting DNS info?
you can add the DNS info.  I think systemd-resolved is supposed to be
should get all requests.
Where do I see those logs? If I run systemctl status systemd-resolved
than I see this:

vpn0: Bus client set DNS server list to: 192.168.x.x, 192.168.x,y

Now, those two entries are added by the AnyConnect-Client to
/etc/resolv.conf.

I cant figure out, why NM is not doing that...

First, when using NM and the openconnect plugin I'm assuming you've not disabled
systemd-resolved.

So, your /etc/resolv.conf is a symlink on the order of

lrwxrwxrwx. 1 root root 39 Oct 31  2020 /etc/resolv.conf -> ../run/systemd/resolve/stub-resolv.conf

If that is the case, then can you compare the output of "resolvectl" for dis-connected/connected?
I only use openvpn.  But it looks like so:

disconnected

[egreshko@f34k ~]$ resolvectl
