android and ios google sign in using laravel socialite

HI. i am working on a project for android and ios, and i want the users have the option to log using a google account using laravel socialite in the bussiness layer. i was reading some tutorials, and it seems that the way to go is to allow the user to log on google with unity using an api like this and pass the token getted from it to the laravel socialite running in the bussiness layer. Can someone to confirm this or i am missing something ?
Any help or guidance about this topic will be greatly appreciated

Thanks in advance
