How can I make Authentication Service works with WebGL Build.

I am developing a game for my client who first asked me to develop a game for Android. the game also include other Unity Services like Lobby, Relay and Netcode for gameObjects.
But now he is asking me for webGL build. I need Authentication to be implemented as it is necessary for other services like Lobby. So how can I achieve my results??

Hello,
Authentication supports WebGL, you should have no issue using it.
Same for lobby!

Thanks buddy
