question about google sign in plist file

Hi.
i have a question: i am working on a project for android and ios, that needs to allow the user log in with google. i am using the api on this link . and is working fine on android. Now i need to build on ios, but i did read that is needed to locate a .plist file (i got the plist file from google cloud) on the xcode that unity generates. i am not sure where to put the plist file, because on some forums i did read that it needs to be on the root of the xcode project, but in other forum i did read that the plist file have to be on the assets folder of the unity project folder.
Do i need to put the plist file on the assets folder and in the root of the xcode project too ?

any help will be very appreciated.

 

First you have to download "GoogleService-Info.plist" from this link
Click on "created an OAuth client ID"
and chose your project like this , if you don't see any project then click on create a new project then follow a few step to download the file, after that put your file in unity inside (Assets) like this image

I suggest you read this article from Google

hope that can help you
