Unity 2018.1.6f1 External Tools

Hello,
I have just installed Unity 2018.1.6f1 using the Linux Assistant.
When I first opened Unity and tried to open a C# script i saw that i had no External Script Editor.
I installed Visual Studio Code from flatpak and i went to Unity>Edit>Preferences>External Tools and it tells me to Browse… for the editor

I don’t know the location/file i should select in that window.
I have tried multiple files but VSC doesn’t start in it.

The desktop link is ran with “/usr/bin/flatpak run --branch=stable --arch=x86_64 --command=code --file-forwarding com.visualstudio.code --reuse-window @@ %F @@”

More than that i have bloated my dropdown list with files that don’t work:

What should i do to actually select the correct VSC file?
And what should i do to remove the items in that list?

I don’t know how to clear the list there but what about making a simple script that executes your flatpak command?
