g_openuri_portal_open_uri_async: Does not accept a xdg-activation token
From the docs: https://flatpak.github.io/xdg-desktop-portal/docs/doc-org.freedesktop.portal.OpenURI.html can accept an activation token and there is no way to open an uri passing such token.
EDITED: I am not sure where this should be addressed, but ideally g_app_info_launch_default_for_uri_async
should be able to generate a xdg-activation token from the GAppLaunchContext.
