Native mobile auth via Google id_token

Hi, I'm building a native iOS app using Base44 as backend.
Currently, backend functions cannot create valid web sessions due to the lack of access to the session store, and existing auth flows are web-only (redirect-based).

It would be extremely valuable to have a native mobile authentication endpoint that:

• Accepts a Google id_token obtained via native Google Sign-In (iOS / Android)

• Verifies the token server-side

• Creates a valid Base44 web session

• Returns a session cookie usable by the dashboard / web views

Example:

POST /api/apps/{app_id}/auth/mobile/google
Body: { "id_token": "<JWT>" }
Response: Set-Cookie + { "ok": true }

This would unlock clean, secure authentication for native mobile apps without fragile workarounds and would benefit anyone building iOS/Android apps on Base44.
