Shouldn't add buttons be bigger?

I usually need to go slower in order to click this small arrow, and is like a papercut, it really doesn’t need to happen, but it’s kind of uncomfortable to be more precise than usual to click an option that is so small for every filter layer i want to add (also the icon inside the button is too small to my liking), is there a way to change this, maybe make both buttons share 60% and 40% or half and half space each?


I guess it depends on the screens in my case they are very big, I would make all those buttons smaller.
