How to Show a tooltip on a boxplot without hovering over


I am using a double box-plot chart with angular 8. I have a page with 4 d3.js plots as well(I built this particular one with plotly because it was way easier to build than d3).

I have a requirement to show a tool-tip upon a general filter; upon adding the filter all the charts would show tool-tip for the datapoint. This was pretty convenient with d3, but have no clue how to reproduce with plotly.
Any outlier present on the chart should show tool-tip, how can this be achieved with plotly?
