How to use VK Method messages.getByConversationMessageId in php?

Question

PHP

Recently I noticed that new methods appeared in VK, I tried to test them, but it gave out emptiness.
I made a request like this:

$vk->request('messages.getByConversationMessageId', ['peer_id' => $peer_id, 'conversation_message_ids ' => $тут полученную ПЕРЕМЕННУЮ с Jason от вк?, 'group_id' => $gr_id ]);

If I get the message id, does this mean that it will be possible to work with the methods of deleting sms, pinning, editing, etc.?
