How can I get a list of terms separated by comma from a taxonomy field?

I’m actually getting the taxonomy field from a taxonomy term and wish to get each terms’ slug from the taxonomy field.

So far, I’ve got

<?php
$filters = get_terms( array(
   'taxonomy' => 'filters',
   'hide_empty' => false,
   'orderby' => 'term_id',
) );

foreach($filters as $filter):

   $filter_taxonomy = $filter->taxonomy;
   $filter_id = $filter->term_id;
   $filter_fields = get_field('filter-fields', $filter_taxonomy . '_' . $filter_id);

endforeach;
?>

I only need help “extracting” the terms’ slugs from the $filter_fields array and displaying them in a simple array separated by commas.

UPDATE: And I would also like to be able to add the terms’ slugs as classes in a div.

Thanks!

foreach($filters as $filter):
	$filter_fields = get_field('filter-fields', $filter);
	if( $filter_fields ):
		$filter_fields_slugs = array_column($filter_fields, 'slug');
        $data_filter_slugs = implode(', ', $filter_fields_slugs);
	endif;
endforeach;
