Overlays added with .addOverlay not appearing in the viewer.overlays array?

[DevinSmithWork]

I have a project where a user can click a button, which triggers multiple viewer.addOverlay() to highlight a few different places in the canvas. I'm currently working on a "clear" function which removes all of these overlays.

I know I can remove them with .removeOverlay(), but this requires passing an ID -- for my project, a class name would make more sense. I thought I might instead loop through the viewer.overlays array -- however, the newly-added overlays are not included in this array, only the ones I created while initializing the viewer.

Can someone point me to where dynamically-added overlays are stored?

Ah -- never mind, I found it. In case anyone come across this Q:

• overlays added with .addOverlay are stored in viewer.currentOverlays
• This array can be emptied to clear them all... however, you'll also have to manually remove the HTML elements. In my case I'm using document.getElementsByClassName() and removing them from there.
