How to obtain user telemetry (from the client side)?

I checked both the documentation and the forum but couldn’t find the answer I was looking for. I wonder about how to obtain user telemetry to learn about how they use the dash app? What I wonder is about the interaction on the client side mostly, not using the debug=True on the server/dash app. I thought that there must be an easy way to do it rather than customizing components. Thank you
