Point Root Domain to Playit.gg Tunnel (without Subdomain)

Hi,
I’m successfully using Playit.gg with a subdomain like mc.xxx.games via an NS record.

Now I’d like to have my root domain xxx.games point directly to the tunnel – so users can connect (e.g. in Minecraft) just by typing xxx.games, without needing the mc. prefix.

Unfortunately, I can’t use a CNAME on the root domain due to DNS limitations, and I don’t want to delegate the entire root domain via NS, or rather because I cant

My questions:

  1. Is there any way to connect the root domain xxx.games directly to the tunnel – e.g. using SRV or any other method?
