Adds the Lenis library (by darkroom.engineering) to your WordPress page. Simply enable the plugin and it will add the library to your page.
You can use a function ‘smoothScrollLenisCallback(event)’ in your custom code that will be called by the Lenis scroll event.
Note: if you have popup with scrolling content you’ll need to add this attribute <code>data-lenis-prevent</code> to the popup.
