Provide jitsi authentication

I am using jitsi in the docker and want to provide authentication for the first user that joins the call.
I am able to set the authentication inside .env file:

ENABLE_AUTH=1

and I am also able to receive the popup, but where do I enter my own custom credentials? Where do I find the document?
I am using Windows.

Did you create a Prosody user?

I tried doing it this way:

docker-compose exec prosody prosodyctl --config /config/prosody.cfg.lua register user meet.jitsi password

but prosody is not available on windows. What is the alternative? Is it possible to open a file and add list of users and passwords?
