Advanced Custom Fields—Custom location rule that matches custom taxonomy - ajax

Question

I am using the Advanced Custom Fields plugin on a WordPress site. I am aiming to have a custom location rule to show the custom filed group when any term within a custom taxonomy is selected.
Following the custom location rule tutorial on the ACF site I have added custom types, operators, and values to the rules row.
My matching function (code below) works only when the page is reloaded, but not via AJAX. How do I add custom taxonomies to the $options array so the matching function can evaluate via AJAX when custom taxonomy terms are checked/unchecked.
function acf_location_rules_match_taxonomyTerm( $match, $rule, $options ){
// vars
$taxonomies = get_object_taxonomies( $options['post_type'] );
$terms = $options['taxonomy'];
// not AJAX
if( !$options['ajax'] ){
// no terms? Load them from the post_id
if( empty($terms) ){
if( is_array($taxonomies) ){
foreach( $taxonomies as $tax ){
$all_terms = get_the_terms( $options['post_id'], $tax );
if($all_terms){
foreach($all_terms as $all_term){
$terms[] = $all_term->term_id;
}
}
}
}
}
if($rule['operator'] == "<==>"){
$match = false;
if($terms){
$current_terms = get_the_terms($options['post_id'], $rule['value']);
if ( $current_terms && ! is_wp_error( $terms ) ) {
$current_term_ids = array();
foreach ($current_terms as $current_term) {
$current_term_ids[] = $current_term->term_id;
}
}
foreach ($current_term_ids as $current_term_id) {
if( in_array($current_term_id, $terms) ){
$match = true;
}
}
}
}
else{
$match = false;
}
}
return $match;
}
