Plugin Elementor: How can I integrate an audio player in the popup?

The popup function of Elementor still seems to have some minor difficulties, so you have to help yourself here and there. If you want to integrate a simple audio player in the popup, the WordPress own embed code does not work properly. Alternatively, this can be solved with the following script.

<audio controls autoplay>
<source src="datei.mp3" type="audio/mpeg">
Sorry, your browser does not support the audio player.
