Lightbox vs Dialog layer vs Layer Layer
So I get this: https://articulate.com/support/article/Storyline-360-Dialog-Layers
And I get this: https://articulate.com/support/article/How-to-Create-Lightboxes-in-Articulate-Storyline-360 and/or https://community.articulate.com/articles/all-about-lightboxes-in-storyline-360
And a lightbox is a SLIDE. And a dialog layer is a LAYER.
So I guess I'm more confused about the need for (or function of) a "dialog" layer? Isn't it just a slide layer with a pre-added, covered/colored background of the layer? (that you can customize in certain ways as explained in the Customizing the Layer Background Color SECTION of Storyline 360: Dialog Layers ). And, that the dialog layer's background is the entire player.
It seems like functionally, you still need a trigger to Show (Dialog) Layer somehow, and still need a way to close (triggering a ) "Hide Layer".
Am I missing anything else? I feel like I'm missing something. What am I missing? Is there another discussion thread that talks about this? Or an article? Or even a training.articulate.com somewhere.
(I can't believe I was a Beta Tester for Storyline 2, and I can't figure this out! 😟)
