Pass org_id to Google Identity Platform


We’re using Auth0 as the OIDC provider in the Google identity platform.

Though we want to pass the organization ID of logged in users, neither OAuth flow nor using the OIDC provider ID token works. The former is because we can’t/don’t know how to pass the organization ID to the Identity platform, and the latter is because we could pass ID token which includes the user’s organization ID but we also need to pass the raw nonce which we don’t know how to get.

I would appreciate any comments or suggestions.
Thank you.
