To Reproduce How, and what happened?

1. quit the multipass systray if it auto-started
2. open Multipass from the Launchpad

Expected behavior No icon in the dock for the systray app. Otherwise, a proper icon.

I was able to resolve locally by copying the Multipass logo image to my clipboard, opening Get Info on the file missing the image, clicking the broken icon (so it gets a blue highlight around it), then pasting in the image from my clipboard. It's a little-known MacOS feature that you can replace the icon for anything this way. Doesn't persist across updates, but works as a local preference.

I also found it odd that the application sticks in both the dock and the toolbar when open, so I edited the Info.plist inside the package contents and added

<key>LSUIElement</key>
</true>

before

</dict>
</plist>

This hides the application from the dock but keeps it in the toolbar. Less clutter!
