Have an image opened with image you want to turn into icon and have that layer active.
Resize Canvas to size of icon you want surrounding your image.
Run plug-in. Change color to alpha color to color of your image's surrounding background that you like to make transparent to reveal a silhouette. Select icon's color and slightly darker color. Click OK to run.
After plug-in finishes, Change Opacity of "Silhouette" layer to your liking.
Here's a sample before and after.

Tin, I believe I am following your instructions but maybe not as the script begins to run but stops and gives error message before it finishes. What might I be doing wrong? Using Samj's 2.10.12 Windows 10 64.

Not sure what went wrong it looks like the gradient fail. it should be from color to slightly darker color.
Try setting changing your blend tool defaults.
UPDATE: looks like Something wrong with layerfx.py call.
That has happened to me a couple of times with the plugin but I didn't get any errors. Just a gradient when I had only used the two colors. Now when I have tried to re-create it, it works perfectly.
It is a nice pugin !
