I am trying to use google identity platform for my application by following the below link Google Identity Platfrom
But on this page, no identity provider mentioned for LinkedIn and same is not searchable on web.
What I understood is Google's Identity platform is using Firebase underneath. I am just wondering, on Firebase portal it is mentioned that a custom implementation is required for LinkedIn whereas under the GCP account -> Add provider I can see LinkedIn.
What I would like to know is, if it is possible to add LinkedIn as provider out of the box under identity platform.
