I linked the source but sure, I’ll link it more for you.

The portal code is here: github.com/refi64/zypak/…/flatpak_portal_proxy.h

The actual code that Chromium calls is here: github.com/refi64/zypak/blob/…/spawn_latest.cc#L2…

This calls the org.freedesktop.portal.Flatpak service.

This service is here: github.com/flatpak/flatpak/tree/main/portal

The Spawn method creates a new sandbox completely isolated from the originating sandbox.
