Show entry icon in the sidebar menu

Is it possible to show an icon in the sidebar menu next to each entry where the pages are listed?
I’m using the st.navigation for that and I’m passing a list of st.Page-s created like this
st.Page("subpages/my_page.py", icon="<an_emoji>", title="My Page", url_path="my_page")
The icon set in the st.Page object is shown in the title. I would like to show it also in the sidebar menu. Is it possible?
