Copy configuration of another existing Nextdns

Can we copy another nextdns configuration?, but we only know the "DNS-over-TLS/QUIC" which looks like this "e9c975.dns.nextdns.io"

chronology: I found a DNS-over-TLS/QUIC like the example above in the Telegram group, and it is very convenient to use, but the person only provides it for 1 day, so if possible I want to copy it, but I don't know how to find out the configuration, I have asked the creator but he doesn't want to share it... is there another way to find out the configuration?
