Build option :output-wrapper ignored

[sigmasoldi3r]

Attempting to use this build.cljs file:

(require '[lumo.build.api :as b])

(b/build
  "src"
  {:output-to "out/lib.js"
   :output-wrapper true})

Produces apparently no changes in output sources.

The option is described here: https://clojurescript.org/reference/compiler-options#output-wrapper

I'm trying to use this option in spite of producing a multiplatform bundle library for my projects, as I want to consume the library from other JS target languages.
