Retrieve list of filters being applied to a query through Custom Visualization V2

[DevDaDev]

I am building a Custom Vis using the custom_visualizations_v2.

I am trying to retrieve a list of current filters applied to my query.

The queryResponse Param is where I thought this should be. There was some filtering Meta-Data but it all said null. also there was array of field objects under fields key in queryResponse. it has an is_filter param but it always says false even when I think it should be true

Recap. If I am running my custom vis, and apply a filter in the Explore UI. How can I identify a filter in my custom vis code?
