Crop API - Crop Updates and Entity Share

Problem/Motivation

I'm inquiry about a high-level challenge where I believe the issue lies with Crop API and its support of the JSON API; however, I need some additional information about how entity share registers that there is a change.

If Crop Api added fields like 'changed' and 'created' how would Entity Share pick up that there is a change? I went down a little of rabbit hole today to do this but even after changing the schema to support these new fields and validating that these entries changed and were available in a json request when I went to pull the entity there was no registered change.

This is on a content type where we embed media and then have crop api applied to the media.

I eventually got this to work by using a custom entity update hook, but my gut makes me feel this is a hack rather than a Drupal way especially since the way I found depends on entity_usage.

Should I be looking at a plugin or crop processor for Entity Share?

Any feedback is greatly appreciated

This is the hook that eventually got everything working.

/**
 * Implements hook_entity_update().
 */
function uclahs_custom_entity_update(EntityInterface $entity) {
  if ($entity->getEntityTypeId() === 'crop') {
    $uri = $entity->get('uri')->value;
    if (!$uri) {
      return;
    }

    // Load the file entity from the URI.
    $files = \Drupal::entityTypeManager()
      ->getStorage('file')
      ->loadByProperties(['uri' => $uri]);

    if (empty($files)) {
      return;
    }

    $file = reset($files);

    // Get usages of the file.
    $usages = \Drupal::service('file.usage')->listUsage($file);

    foreach ($usages as $module => $usage) {
      foreach ($usage as $entity_type => $entities) {
        foreach ($entities as $entity_id => $count) {
          $used_entity = \Drupal::entityTypeManager()->getStorage($entity_type)->load($entity_id);

          // If the file is used in a Media entity, find where that Media entity is used.
          if ($used_entity && $used_entity->getEntityTypeId() === 'media') {
            $referencing_entities = \Drupal::service('entity_usage.usage')->listSources($used_entity);

            foreach ($referencing_entities as $source_type => $source_ids) {
              foreach ($source_ids as $source_id => $records) {
                $parent_entity = \Drupal::entityTypeManager()->getStorage($source_type)->load($source_id);
                if ($parent_entity && $parent_entity->hasField('changed')) {
                  $parent_entity->set('changed', \Drupal::time()->getRequestTime());
                  $parent_entity->save();
                  \Drupal::logger('uclahs_custom')->notice('Updated parent entity from media usage: ' . $parent_entity->id());
                }
              }
            }
          }
        }
      }
    }
  }
