Google Slides - How to use "Create a Slide from a Template Slide"?

Okay, actually, I’ve now managed to use the slide ID “g2b0d5a0ff2d_0_142” as “Template Slide ID” (“Page Object ID”) value without generating an error…

I think Output confirms the module picked up the intended source slide to replicate…

But I don’t see any sign of a subsequent new slide having been created.

Still don’t understand how this module is supposed to function.
