How do I use more ipywidgets than just the slider for a popup on ipyleaflet within a shiny python app?

Question

In this demo app, I am trying to get create a popup for when I click on one of the polygons that I have drawn on the map with the geodataframe data. I have tried experimenting with many different ipywidgets to see how the different popups would look so that I can improve on the one that I decide to use. However, for some reason only the IntSlider widget seems to work. Whenever I substitute another widget for the slider widget, all of the polygons that are drawn disappear and there is no longer anything to click on to generate the popup. For now, I am okay with having the exact same popup for each polygon and will adjust that later. Are the other widgets not compatible? Or do I need to make some edits to my code to get the widgets to work?

    polygons = GeoData(geo_dataframe=raw_data, style={'weight': 0.5, 'fillOpacity': 0.1})
    register_widget("my_map", my_map)
    my_map.add_layer(polygons)

    label = Popup(child=widgets.Label("Hello World"))
    text = widgets.Text(value = 'Hello World', placeholder='Type something', description='String:', disabled=True )

    slider = widgets.IntSlider(value = 5, max = 10)
    string = "test"
    polygons.popup = label
