Tutorial: Using Epic Online Services with Lyra Starter Game

In The part 4 of Packaging LyraGameEOS from :Using Epic Online Services with Lyra Starter Game | Tutorial

It says:

"If this process succeeds, it will place a packaged copy of the game in the directory you selected. This packaged build can be zipped up and sent to another computer for real world multiplayer testing. If you were to run this packaged build from the Epic Games Store, it knows to pass the correct user credentials in. But for development testing you will need to make a shortcut or batch file and pass in the -AUTH_LOGIN=localhost:6666 -AUTH_PASSWORD=Player1 -AUTH_TYPE=developer
part of the command line mentioned above.

Maybe that is the reason it does not work in package build. you should pass the account.
i don´t know how to do the batch or shortcut for it.

Also for some reason when i launch 2 standalone games from VS or packaged never see the lobby created by host. But Shift+f3 works even can send friend request even without
DevAuthTool.
Any suggestion?
Thx.
