How can I get a report on Activities tied to leads from Explore?

Hi Prashant!

We have released several Explore recipes that you can use to create a report based on your Leads activities which you can check out here: Zendesk Sell Explore Recipes. Please feel free to customize the reports as you see fit. I also suggest checking out this article which you can use as a reference for metric/attribute calculations. 

Hope this helps!
