Verify Id Token JWT

[mirzaq19]

Hi, I have a question. Is there a way to verify the ID token from /oauth/token? I understand that it's simple just to copy the ID token and secret key and paste them into https://jwt.io/, but I'm not sure which secret key was used to sign this ID token. I've explored the code, but I'm still confused. In this case, I’m using Laravel Passport for the implementation.
