Writing figure to html, figure image not included

Dash Python
1

I have a fully working Dash application with my logo displayed over my chart.

When I use the fig.write_html(…) process, my resulting HTML file does not have my logo over the chart. Some relevant code snippets below. Is this the expected behavior?

fig.add_layout_image(
    dict(
        source="assets/Logo.png",
        xref="paper", yref="paper",
        x=1.014, y=0.79,
        sizex=0.3, sizey=0.3,
        xanchor="right", yanchor="bottom",
        opacity=0.8
    )
)

fig.write_html("file.html")
