Python callback triggered by hover to identify which of multiple lines is being hovered over

Is it possible to hover over one of multiple plotted lines and trigger a callback that would allow one to identify which line on the graph was being hovered over?

Currently I have 5 lines separately rendered to the plot, however, a solution with multiline would be fine. I’m using bokeh-server and would ideally not use any custom js.
