I can't point my domain, please i need help

Hello I hope everyone is well.

I want to buy one of the packages, but before buying I'm testing all the operation, I installed it on my VPS and it worked well.

But I came across a problem that I can't solve. I created a customer account, and I want to point out to point a pammil for this customer account, it happens I don't know which nameservers use, should I use the nameservers that come there as a standard? It turns out that in my host there is no main dolids.

I created a virtual machine on Google Cloud.
