Log Analytics KQL - How do I track interaction?

Hi,

I have a requirement to see which slicers and visual users are interacting with.

I have Log Analytics set up for my workspace and I am able to see a record for each dashboard visual load (KQL below). I'm importing this data into a PBIX and modeling it with report.JSON to get the names & descriptions of all the visuals.

My next step is to somehow figure out if a user changed a slicer or drilled into a visual or selected a value.  I'm hoping there is a better way to do this than comparing the DAX/EventText. 

If anyone knows, please reply. TIA!
