How can I add annotations to both plots while using facet in plotly express?

I’m using px.timeline to plot gantt charts and I’m using facet_col. There are only two classes so I get have two plots side by side. I add the annotation to the plot after I call the px.timeline function, like this,

fig.update_layout(title=title, showlegend=False, height=3000, annotations=annots)

How should I make this annotation appear in both of the facet plots ?
