Problem with plank dock in manjaro gnome

I recently installed plank and disabled the dock extension present in gnome tweaks.
I want apps to startup from plank dock when i press super + number.
This is not working in the plank dock but they are lanuched from default dock.
Any ideas on how to do it?

According to this post, plank is a 3rd party and doesn’t support the option to set keyboard shortcuts like that.
