Altering Views Exposed Form Elements and their Associated Labels
Should add #attributes to your element form so the form alter should be like:




function HOOK_form_views_exposed_form_alter(array &$form, FormStateInterface $form_state, $form_id) {
    $form['name_of_element']['#attributes']['twig-suggestion'] = $form['#id'];
}




HOOK_theme_suggestions_input_alter will works only with input elements textfield.
