label = LOC("Isn't it time you come clean?");

  LOC("Test"); 

vngen_text_replace(0, "AYRY", label, inherit, inherit, 0.5);

As per documentation, text is auto-extracted if it is a constant string or an expression that evaluates to a constant string.

So if you want to store text in a variable before passing it elsewhere, you’d indeed want to do

var LOC = cmn_loc_get_func("...");
label = LOC("Isn't it time you come clean?");
