How can I load comment IDs using the comment type? I know how to load comment ids for a particular node by following code 

$entity_manager = \Drupal::entityTypeManager();
$cids = $entity_manager
    -&gt;getStorage('comment')
    -&gt;getQuery('AND')
    -&gt;condition('entity_id', '25364')
    -&gt;condition('entity_type', 'node')
    -&gt;execute();


But I need one more condition to add on because this node might have multiple comment type linked. I know the machine name , but I don't know exactly what should be the first parameter to be passed in condition.
I itself got the answer i just guessed the name to be passed in condition.

$cids = $entity_manager
    -&gt;getStorage('comment')
    -&gt;getQuery('AND')
    -&gt;condition('entity_id', '25364')
    -&gt;condition('entity_type', 'node')
    -&gt;condition('comment_type' 'post_trp_comments')
    -&gt;execute();
