ACFVC – Checkbox

There are 4 portfolios at the bottom of the page, above the footer.

These 4 portfolios comes from custom taxonomy: portfolio_category

Visual Composer has an element named “Post Grid” where I can show posts from custom taxonomies. (https://imgur.com/a/rOhp8O1)

Inside this “Post Grid” element, there is an option to modify the way posts are appearing in the front-end (https://imgur.com/a/OkL4Uvn). This “123” template is the one I made inside the Grid Builder of VC (https://ibb.co/eqf8Ke). With this template, i can show the image, title and the category name of the current portfolio (as shown in the homepage).

This is the Custom Field: https://ibb.co/nwGyKe
It uses a Checkbox field type.

This is the options I choose with ACFVC: https://ibb.co/dvEw5K

But in the front-end, I see the category ID, not the category name. I looked the hooks you are providing and there is this: add_filter(‘acfvc_checkbox’,’function_name’,10,3);

How can I use this? Whatever I tried nothing happened.
I tried a simple interaction like this:

add_filter( ‘acfvc_checkbox’, function( $atts ) {
$atts = ‘22222’;
return $atts;
} );

But nothing showed up.
How can I show the category name instead of category ID ?

Thanks in advance.
