Silverblue: .desktop file for container application not working

So, I have installed vscode inside toolbox-container, since flatpak version can’t access libraries installed inside toolbox-container.

And I followed Alex’s youtube tutorial on launching toolbox application from shell.

But it only works when ‘Terminal=true’,
when ‘Terminal=false’ nothing happens, I don’t know what’s happening.

Can you help me solve this problem?

Here’s code.desktop

[Desktop Entry]
Name=Visual Studio Code
Comment=Code Editing. Redefined.
GenericName=Text Editor
Exec=/usr/bin/toolbox run /usr/bin/code
Terminal=true
Icon=com.visualstudio.code
