Comment 34 for bug 1732482

A. Tested https://signals.rotor-rig.com/ with stable version snap x64 (117.0.5938.88):
File chrome-pdplehbldmmknfihajdehomkoigcbhib-Default.desktop was created in ~/Desktop
#!/usr/bin/env xdg-open
[Desktop Entry]
Version=1.0
Terminal=false
Type=Application
Name=Signals
Exec=/snap/bin/chromium --profile-directory=Default --app-id=pdplehbldmmknfihajdehomkoigcbhib
Icon=chrome-pdplehbldmmknfihajdehomkoigcbhib-Default
StartupWMClass=crx_pdplehbldmmknfihajdehomkoigcbhib

No file was created in ~/.local/share/applications . So, it's not possible to find it in the launcher

File icon in desktop has no icon and allow launching needs to be clicked, worked after that. App had no icon.

B. Tested in snap beta (118.0.5993.11)
File was not created in ~/Desktop , so no Desktop Icon

File chrome-pdplehbldmmknfihajdehomkoigcbhib-Default.desktop was created in ~/.local/share/applications
#!/usr/bin/env xdg-open
[Desktop Entry]
Version=1.0
Terminal=false
Type=Application
Name=Signals
Exec=/snap/bin/chromium --profile-directory=Default --app-id=pdplehbldmmknfihajdehomkoigcbhib
Icon=chrome-pdplehbldmmknfihajdehomkoigcbhib-Default
StartupWMClass=crx_pdplehbldmmknfihajdehomkoigcbhib

App was available in Ubuntu Launcher.
C. Tested in edge (118.0.5993.11)
Same behavior than Beta, file in ~/Desktop was not created but it was created in ~/.local/share/applications

In all 3 cases the dock never showed the App icon when I opened the app but the Chromium Icon. I don't know if this could be fixed as if I open any PWA and then I want to open Chromium, it will show the PWA window and not open a Chromium window.
