v2 API: user session metadata in Zitadel's action?

❓Question➕Feature Request✅Solved

As the title says, is it possible to create a user session using v2 Beta API where some custom metadata are added, and later when creating id_token I would like to trigger action that somehow reads user session metadata and appends custom claims to id_token?

So, I would like to use session metadata in Zitadel's action when session token is exchanged for code (OIDC flow in custom login UI):
