How to have a reference to the model within the draw function of a DrawArea

[LevitatingBusinessMan]

Let's say I want to modify the counter example by drawing the counter in a DrawingArea instead of a label.
The DrawingArea widget will have to be configured with a draw function. However ideally this draw function would make use of the state of the app.

What would be the most appropriate way to ensure that the draw function has a (read) reference to the model?

#[relm4::component]
impl SimpleComponent for App {
    type Init = u8;
    type Input = Msg;
    type Output = ();

    view! {
        gtk::Window {
            set_title: Some("Simple app"),
            set_default_size: (300, 100),

            gtk::Box {
                set_orientation: gtk::Orientation::Vertical,
                set_spacing: 5,
                set_margin_all: 5,

                gtk::Button {
                    set_label: "Increment",
                    connect_clicked => Msg::Increment,
                },

                gtk::Button {
                    set_label: "Decrement",
                    connect_clicked => Msg::Decrement,
                },

                gtk::DrawingArea {
                    set_draw_func: |area, ctx, height, width| {
                        cairo_show_text(model.counter);
                    },
                }
            }
        }
    }
}

I think this is can be solved with abstractions::drawing as shown in https://github.com/Relm4/Relm4/blob/main/examples/drawing.rs
