Choose Google account on SSO?

I am wondering, when I configure Google IDP: if I start an OIDC flow from UI, if I'm not logged into Google, it shows the view to do so. But if I am already logged in, and I start the OIDC flow, it just used that google session. If I have more than 1 Google account logged in, it still just proceeds with the first session. How can I configure zitadel to send something to Google, to list the Google accounts (even if there's only one session) to let the user choose which one to use to log in?

Hi @Gaia, I'm an AI assistant for ZITADEL. While a team member reviews this question, I'll see if I can find relevant sources for your question.

Answer

I wasn't able to find a direct answer, here are some relevant sources:

Only allow users from a specific Google workspace (Google OIDC Authenticator) : This discussion mentions that custom parameters like Google's hdhd parameter are not currently supported from the ZITADEL side, but suggests using ZITADEL Actions v2 to modify authentication flows.
Configure Google as an Identity Provider in ZITADEL : This guide covers the basic Google IDP configuration but doesn't address account selection parameters.
