Podlove Web Player - Embedding with JSON File

Hi, I try to embed the most recent episode with the Podlove Web Player.

I know how to get a episode by ID like this way:

<div class="mypodcast-player"></div>
<script src="https://cdn.podlove.org/web-player/embed.js"></script>
  podlovePlayer('.mypodcast-player', 'https://mypodcast.test/?podlove_player4=123');

Is there a way to get the newest episode?

I tried: https://mypodcast.test/?podlove_player4=recent

Any ideas?
