Play custom map with friends

So I've made a fantasy map with some friends, not for this game but just for fun. Now I've made this map into a custom atWar map and I'd like to play on it with my friends. I have a premium account, but they don't play atWar so they would end up in the beginner's lobby. I can't host a game in the beginner's lobby and they can't join the main lobby. If I make a new account it won't be a paid account. How do I play this map with my friends?

I'm not sure if this was fixed or not but if you copy and paste the url of the game you hosted and send it to them then they might be able to join

They are allowed to play in the main lobby. It's just foolish if they can't play with high ranks. Make a private game there and share the password with only your friends.

Yes, @WhatViruslegion wrote, create a game in the Main room, and share the link with them.
