/**
 * Implements hook_entity_operation_alter().
 */
function hook_entity_operation_alter(array &$operations, EntityInterface $entity) {
  if (!$entity instanceof MenuLinkContent) {
    return;
  }
  // Alter the title of the edit link appearing in operations menu.
  $operations['edit']['title'] = t('Altered Edit Title');
}

How to add a new operations link

/**
 * Implements hook_entity_operation().
 */
function hook_entity_operation(EntityInterface $entity) {
  if (!$entity instanceof MenuLinkContent) {
    return;
  }
  $operations['custom_operation'] = [
    'title' => t('Custom Home'),
    'weight' => 20,
    'url' => Url::fromRoute('<front>'),
  ];
  return $operations;
}
