How to not duplicate icon in the Ubuntu dash?

[sharpordie]

Expected behaviour

Shortcut in the dash should not create new dash icon on start.

Actual behaviour

When I click on the icon to start the VM in the dash, it creates a new icon.

Steps to reproduce the behaviour

I have created .desktop shortcut.

quickemu --vm macos-monterey.conf --shortcut

And I have changed the .desktop icon.

desktop="$HOME/.local/share/applications/macos-monterey.desktop"
sed -i "s/Icon=.*/Icon=distributor-logo-mac/" "$desktop"

I have pinned the shortcut to favourite.

Unfortunately when I click on the icon to start the VM, it creates a new icon in the dash. Is there a way to not duplicate icon in the dash when running quickemu VM?
