Tested, looks good !

Only issue I have found is that on my side events are duplicated and sent in pairs (the component is rendering/mounting twice [and sending tracking events twice ] ?) But this also the case for existing events (like dataset_open)

Maybe we want some throttling on those trackEvent calls

Maybe we want some throttling on those `trackEvent` calls

Thx, ^-^! Yes, It's due to react.StrictMode (enabled by default on dev environment) that re-render the component twice. Good idea for the throttling, to explore !
