Google: If app runs on multiple platforms, each will need its own client ID.

Hello! How may I specify different Google CliendId, if my application runs on several platforms? From Google Cloud -> Create OAuth client ID:
A client ID is used to identify a single app to Google's OAuth servers. If your app runs on multiple platforms, each will need its own client ID. See [Setting up OAuth 2.0 ](https://developers.google.com/identity/protocols/oauth2/) for more information. [Learn more ](https://support.google.com/cloud/answer/6158849) about OAuth client types.

Or, as we use proxy - it is not necessary? And then I should create only one Apllication type client Id - for example - Android, and use it for every authentication where Google is chosen as provider?
