PWAs create invalid .desktop files

[kees-closed]

When creating a PWA, it creates an invalid desktop file:

#!/usr/bin/env xdg-open
[Desktop Entry]
Version=1.0
Terminal=false
Type=Application
Name=Microsoft Teams
Exec=flatpak 'run' '--command=/app/bin/chrome' 'com.google.Chrome' '--profile-directory=Default' '--app-id=cifhbcnohmdccbgoicgdjpfamggdegmo'
Icon=chrome-cifhbcnohmdccbgoicgdjpfamggdegmo-Default
NoDisplay=true
StartupWMClass=crx_cifhbcnohmdccbgoicgdjpfamggdegmo
X-Flatpak-Part-Of=com.google.Chrome
TryExec=/var/lib/flatpak/exports/bin/com.google.Chrome

When running this validation tool, it complains about the following:

This is fixed when changing the Exec to:

Exec=flatpak run --command=/app/bin/chrome com.google.Chrome --profile-directory=Default --app-id=cifhbcnohmdccbgoicgdjpfamggdegmo

Both Exec's work, but only the latter Exec is valid according to the desktop-file-validate tool.

I'm using version 131.0.6778.204-1 of the Chrome Flatpak on Fedora Silverblue.
