    Provide org.freedesktop.impl.portal.access implementation
    
    If a sandboxed app requests access to some system resource (camera,
    microphone, location), the portal frontend needs to ask the user
    for permission. In GNOME, we want this to be a system modal dialog,
    so provide an org.freedesktop.impl.portal.access implementation
    that exposes a generic system modal permission dialog on the bus.
