Spotlight using JavaScript and Alt Text

I created a spotlight feature, with some help from AI, to focus on specific areas of the screen in e-learning. I didn't create it for spotlight interactive gaming scenarios. I use it for software focal areas. You can add a shape or multiple shapes to your slide and add alt text, and JavaScript on the master slide recognizes the text. It currently works with circles, ovals, rectangles, squares, and rounded-edge shapes. However, I couldn't get triangle or star shapes to work.

You can also change other features. For example, you can adjust blur and Mask color and apply them to a button to toggle them on or off. 

Let me know your thoughts. I provide a step-by-step guide in the downloadable storyline file.
