Add quantity next to categories?

Does anyone know how to get a quantity of total items to show up next to each category in Parenthesis? I can't find this anywhere. I'm using 2.3 professional. I would appreciate any help.

You could do this

Their website says "[color=#515151][font=Arial, sans-serif][size=3]Compatible with CS-Cart [/size][/font][/color]Professional, Ultimate and Multi-Vendor [color=#515151][font=Arial, sans-serif][size=3]versions[/size][/font][/color]2.0.x-2.1.x. " So I don't think it will work.
