SUMMARY
In Flatpak applications which can install custom desktop launchers at run time using the Dynamic Launcher portal, trying to install a launcher using the portal fails, and a notification saying 'Portal closed unexpectedly' appears. Specifically, the call to dynamic_launcher_prepare_install_finish() fails.

Launchers created in GNOME fail to launch as well, with a notification saying 'you are not authorised to execute this file.' The launcher, located at ~/.local/share/applications/name.desktop, is a symlink to ~/.local/share/xdg-desktop-portal/applications/name.desktop which is not executable by when created by the portal in GNOME. Making this file executable solves the problem.

STEPS TO REPRODUCE
1. Install https://flathub.org/apps/net.codelogistics.webapps
2. Click on add new web app and install any website

OBSERVED RESULT
The dialog to install the launcher does not appear, the launcher is not installed and a notification saying 'Portal closed unexpectedly' appears.

EXPECTED RESULT
The portal's inerface asks to install the launcher and the launcher gets installed.
