Rename comments labels in WP admin - wordpress

Question

Is it possible to change default comments in wordpress admin?
I`d like to rename comments into testimonials everywhere in admin.

If you want to change all WordPress uses of 'Comment', then you need to hook into the translation filter
is_admin() && add_filter('gettext', function ($translation, $text, $domain) {
if (strpos($translation, 'comment') !== FALSE) {
return str_replace('comment', 'testimonial', $translation);
}
if (strpos($translation, 'Comment') !== FALSE) {
return str_replace('Comment', 'Testimonial', $translation);
}
return $translation;
}, 10, 3);
But that changes EVERYTHING that runs through gettext.
If you just wanted to change the admin section title you would do this:
add_action('admin_head', function () {
global $wp_meta_boxes;
if (!empty($wp_meta_boxes)) {
foreach ($wp_meta_boxes as $page => &$positions) {
foreach ($positions as $context => &$priorities) {
foreach ($priorities as $priority => &$boxes) {
foreach ($boxes as $id => &$box) {
if ($id === 'commentsdiv') {
$box['title'] = 'Testimonials';
break;
}
}
}
}
}
}
});
Beyond that, you'd have to find every instance of 'Comment' and see if there was an associated hook for that situation. I'm not sure if that is feasible.
