Reduce tray icon padding on Ubuntu with GNOME 3

All of my tray icons have a higher than normal amount of padding on Ubuntu 19.04.
enter image description here
Is there any way to tweak this value?


Solution 1:

As suggested by @pLumo, 'Status Area Horizontal Spacing' GNOME extension fixed my problem.

Solution 2:

Another possibility would be to use Unite Extension which fixes this issue and provides many other improvements for the Unity-lovers.

Unite is a GNOME Shell extension which makes a few layout tweaks to the top panel and removes window decorations to make it look like Ubuntu Unity Shell.
