Best reports for tracking Answer bots success rates

Hey all,

We just moved to Workspaces and enabled messaging instead of chat. As a start what are most of you monitoring after building your decision trees? 

I am however looking for the following as a start (The canned dashboard isn't helpful): 

• Ability to drill into flows. Eg. if a customer clicks Billing and Payments, need to see what most of them clicked next
• Drill into what flows were resolved by the flow and not transferred to an agent
