The run_app() function in {golem} returns an object of class shiny.appobj, as far as I understand, since this is what is returned by with_golem_options() with the default parameter print=FALSE, inside run_app(). How does this object get "printed", i.e. the app executed?
I do not see any difference in calling with_golem_options() with print=FALSE or print=TRUE. In both cases, the shiny app starts normally.
