Is there a way to have 2 icons when using elixir-desktop?

Unfortunately for me, using:

{Desktop.Window,
       [
         app: :web_interface,
         id: WebInterface,
         title: "Market Manager",
         size: {900, 960},
         menubar: MenuBar,
         icon: "static/images/resized_logo_4.png",
         taskbar_icon: "static/images/resized_logo_5.png",
         url: &WebInterface.Endpoint.url/0

Still results in the icons being the same:

I believe to be using the latest version as well:

# Project deps
{:desktop, "~> 1.4"},

mix lock

"desktop": {:hex, :desktop, "1.4.2", "48cb5f02aa77522bd9996bfe02c4b23f8dc40d30076ada46b660f4a20bd7a3a1",
