Graph Security sample event data, or sample event generator?

I would like to check if anyone aware of sample events, or built in native sample event generator?
I have collected a few sample events in my own test tenant, but need much more to fully test my app.

I have looked across the various potential sources below, and besides schema, I cant seam to find comprehensive sample event data - or a way in of the integrations below to generate any or random events with dummy data.  Any ideas?
