Google Play Service for unity web/webgl player

Hi I have a game (IOS/Android) both running google play service using the unity plugin. I have hosted the game in web using unity webplayer as well as webgl preview player and am able to play the game there. I have created the google client id for the webplayer. The official GitHub - playgameservices/play-games-plugin-for-unity: Google Play Games plugin for Unity doesnt have instructions on enabling the web service through the plugin. Has any one implemented this. Not able to find any relevant answers on the web.

I’m wondering the same thing. Any help would be appreciated.

i am also implementing same thing. but still could not find solution.
