Improve module documentation and provide screenshots

Problem/Motivation

What exactly does this module do and help with? Does it provide visual reports? Or data? Or does it track events?

This isn't really clear from the current description.

I'm thinking about an integration with posthog module, but no idea if this fits... could you perhaps add more details?

Thanks!!
