hide the left-column on a single category page

[Andy-BX]

Hallo,

I really need your help, I would like to hide the left-column on a single category when the page of this category is displayed. Let me explain better I have activated in the dashboard-> design-> theme and logo the layout with left column + central column for category pages. but for a specific category I would like to display only the central column, and hide the left one.

I suppose I have to add a {if} to test the category and act accordingly, I guess I need to edit a .php or .tpl file, can somebody of you tell me what this file is named, or what is the best way to proceed with get this result. I'm using Prestashop 1.7.3

Thank you in advance

class="{if $category->id == XX}hidden{/if}
