Tweaking Unity from the terminal. How to remove an app from the sidebar?

Question

Unity

The command unity --reset-iconsreturns all icons to the standard view. But this is not enough for me, there are still unnecessary elements, for example, the Ubuntu Software Center. How to remove it from the terminal?

Or an approach from the other side: how to set up the very standard position of the icons so that the unity --reset-iconsicons I need appear in the sidebar?
