Plotly Heatmap clickData

Question

I have a heatmap made using plotly.graph_objects.Heatmap . I'm now designing a dash app, which should have the heatmap and a separate text box or graph displaying some data associated with a given heatmap cell. I would like the text box/graph to update based on which cell was last clicked by the user.

Can someone tell me how to access the 'clicked cell data' for a given heatmap cell? I think the equivalent for a graph (which I've seen mentioned elsewhere in answers to similar questions) is dcc.Graph.clickData , but I can't see a clickData attribute for go.heatmap .

Thanks! Tim
