making home_map_taxonomy_walker clickable

ok uhm like i said before im a wordpress noob

but im trying to learn

atm i want to change the categorie list inside the map
i want to make it clickable

this function i found inside
public_html/wp-content/plugins/geodirectory/geodirectory-functions/map-functions/map_functions.php

now i can just simply change that page
on line 253

$out .= '<li>' . $term_check . '<label for="' . $map_canvas_name.'_tick_cat_'. $cat_term->term_id . '">' . $term_img . ucfirst($cat_term->name) . '</label><i class="fa fa-long-arrow-down"></i>';

and then make a link from it, directly in script

but i want to learn how you guys would do it with snippets

is someone willing to show me? or do i just edit it inside the php
