Install Jonnitto.Plyr


it has been 2 - 3 Years that I did some sites, and i completely forgot about installing plugins the right way.

I would like to use the Jonnitto.Plyr Plugin (jonnitto/plyr - jonnitto - ☰ Extensionpakete & Plugins - Download - I installed it with composer, but what do i have to do to add it as a selectable Module?

I remember that i have to create a NodeType for it but how to reference the plugin the correct way?

Thanks for your help!
