How to use Jitsi meet installed locally

Hi guys,
I already installed Jitsi meet in a server running Ubuntu 18.04, something like this: https://meet.example.com.
My question how to call from script? Or do you have any manual to do that?
Before I was using this call https://meet.jit.si/external_api.js and now I am using

But when the conference is open the link to share is:
meet.jit.si/session123
I think i doing something wrong.
thanks in advance.

make dev

Hi, I don’t understand your suggestion. Please advise.
