How to use Google Access Token to call Google Drive API

I’m using Firebase Authentication mechanism and the scope I have provided https://www.googleapis.com/auth/drive

While running application, it asked for user login along with user's consent for Google drive access. After successful authentication it returns a Firebase Id Token.

In the next step application requires to access user's Google Drive. As I know Google Drive API requires OAuth Access token while application has Firebase Token.

**My questions is**: How to generate OAuth Access token which is capable to access user's Google drive? OR Is there any alternate solution for this?
