Need help for app.changeCurrentPageBackground()

[Shogun05]

I am trying to make a plugin that will default the background of a page to a dark mode page. This is me touching lua for the first time so i am not sure how to go about the app.changeCurrentPageBackground();

The current I have right now in main.lua is:

function initUi()
    app.registerUi({["menu"] = "Dark Mode", ["callback"] = "darkMode", ["accelerator"] = "<Control><Shift>b"});
  end

  function darkMode()
    app.changeCurrentPageBackground(":image");
  end

Now i have an image, bg.png which is what i wish the background to be. How do I pass arguments into the method to do that?

It looks to me like the API doesn't support that yet. Basically we need

page->setBackgroundImage(newImg);
page->setBackgroundType(PageType(PageTypeFormat::Image));

and we only get the second step via app.changecurrentPageBackground(":image").
