How to get ID token

[djolec987]

Hi all, I'm wondering is there a way to get the JWT?

I have my backend in spring boot, and I want to send the JWT in the Authorization header for authentification (I'm using Google as IDP, I do NOT want to access Google's API).
So I need the JWT, but all I can get is an access token.

Any ideas how I can obtain the JWT?

Thanks in advance!

Edit
Sorry, I should have been more precise...
I'm following this tutorial (useTokenClient).
