hook_entity_prepare_view($entity_type_id, array $entities, array $displays, $view_mode)
Act on entities as they are being prepared for view.
Allows you to operate on multiple entities as they are being prepared for view. Only use this if attaching the data during the entity loading phase is not appropriate, for example when attaching other 'entity' style objects.
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.

if (!empty($entities) && $entity_type_id == 'user') {
// Only do the extra work if the component is configured to be
// displayed. This assumes a 'mymodule_addition' extra field has been
// defined for the entity bundle in hook_entity_extra_field_info().
$ids = array();

if ($displays[$entity->bundle()]->getComponent('mymodule_addition')) {
