Parameters

string $entity_type_id: The type of entities being viewed (i.e. node, user, comment).

array $entities: The entities keyed by entity ID.

\Drupal\Core\Entity\Display\EntityViewDisplayInterface[] $displays: The array of entity view displays holding the display options configured for the entity components, keyed by bundle name.

string $view_mode: The view mode.
