Applying a layer style from the library

[BillScurry]

Can anyone tell me how to actually apply a layer style from a library? I have a drop shadow style I like to use over and over again, but after saving it to the library I can't seem to use it. There's nothing to drag, and clicking two, three, 500 times does nothing. I can't believe I need to ask this, since there isn't a single word about actually "using" library items anywhere I could find on Adobe.com.

Clicking the Style’s icon in the Library works fine for me. 

Could you please post screenshots or a screen recording with the pertinent Panels (Toolbar, Layers, Libraries, Options Bar, …) visible?

After trying how you do it, I realize I'm not getting consistent behavior from my app. A quarter of the times I try to click the library item, something happens, but the rest of the times it's inert. I don't think recording the action would be illustrative now, but thanks for your suggestion.
