How to get additional data from Access Token URL request in OAuth 2.0 Authorization process?

I’m trying to get id_token from LINE Login process using OAuth 2.0 with Authorization Code Flow. I can only get the access_token from this process by this code snippet:


I’d like to access the id_token but it’s been bundled with the Access Token URL request. I don’t know how to access it.
