How to test a website

SYSTEM INFORMATION
OS type and version AlmaLinux 10.2
Virtualmin version 8.2

Another question: I need to transfer domains and websites from the ISPConfig managed VPS (old provider) to the Virtualmin managed VPS (new provider). I started with a domain which is unimportant. So I installed the Virtual server with that domain name and transferred the domain to the new provider. They say it takes up to 24 hours for the transfer to take effect. I would like to test the website before it happens (that is particularly important for other domains which need to be transferred). Is it possible to do that? What kind of URL would I have to enter in the browser in order to see the website that is on the Virtualmin managed VPS? Or will it only work once the domain has been transferred?

Never mind, found it!
