Remove distraction free mode from teeny editor

Question

I'm trying to remove the distraction free mode button from the editor, but i can't make it disapear.

Here is the code im using:

  add_filter( 'wp_editor_settings', function($settings) {
    $settings['teeny']=true;
    $settings['media_buttons']=false;
    $settings['quicktags'] = false;
    $settings['dfw'] = false;
    return $settings;
  });

Is there something i'm missing? Because this works on the regular editor.

Thanks!

Answer 1

So after researching some wordpress filters i found the teeny_mce_buttons and removed the distraction free button with this function.

  function remove_teeny_mce_btns($buttons) {
    unset($buttons[13]);
    return $buttons;
    }

    add_filter('teeny_mce_buttons', 'remove_teeny_mce_btns');

Here is the link with the solution:

Answer 2

function allow_distraction_free( $expand, $post_type ) {
    return false;
}

add_filter( 'wp_editor_expand', 'allow_distraction_free', 10, 2);

This tested and works as per https://developer.wordpress.org/reference/hooks/wp_editor_expand/ and via https://gist.github.com/jwondrusch/41130a421a2a70b0e697 found by googling 'disable distraction free mode'. The link offers example to tailor by post type.
