Add a custom link to the contextual menu of every block

Question

I want to add a custom contextual link on the top of every block. there are many answers available on the site but these answers are about adding a contextual link to a specific block. and I need to add a contextual link which appears in the contextual menu of every block available in the site. I have tried this function.

function MYMODULE_contextual_links_view_alter(&$element, &$items) {
  if (isset($element['#element']['#block'])) {
    $element['#links']['animation'] = array(
      'title' => 'change animation',
    );
  }
}

I didn't get what I want.

Answer 1

The syntax of the link element is wrong.

This is a sample from the documentation of the Link render element.

$build['examples_link'] = [
  '#title' => $this->t('Examples'),
  '#type' => 'link',
  '#url' => Url::fromRoute('examples.description')
];

How do I create a link? has several answers with methods to produce the link.
