Hidden Player

Hi there. I need some help. I downloaded the “Speaker-lite” plugin and installed it in my WordPress staging site at Siteground. Although I followed all the instructions and the plugin seems to have installed successfully, I can not see the player no matter what I do. I have tried several Assignment combinations – to no avail. Please let me know what kind of information you need from my side so I can check how it performs on my sites.
Side Note: I use Elementor Pro.
