Dock icon

Hi there,
I think the problem is very simple but I haven’t found a solution yet.
I am currently using Thunderbird beta, I created a launcher for the client and put the launcher icon on my dock. When I launch the program, a second icon appears on the dock, but when I launch another program, a dot appears below the launcher icon and no other icon appears on the dock.
Where is my error?

Thanks a lot

Just add StartupWMClass=VALUE_HERE rule in your app’s launcher (.desktop) file should fix the issue.

For Fedora Workstation, you may press Alt+F2 and run lg to get the VMClass values of all opened windows under ‘Windows’ tab.
