Downloadable Client-Facing Activity Report

User Story: 

I am a CRA, and I want to offer my clients the ability to easily export the Activity Report because currently the process is quite cumbersome.

Current Behavior:

Currently, the Client Activity Report data opens in a new tab that cannot be manipulated/sorted. To do so, I have to save the data in a different format by selecting all data from the Activity Report tab, copy, paste into Excel or Google Sheets, which may still require more formatting and cleanup.

Potential Enhancement:

I would like to see a 'Download' or 'Export' button implemented so that my clients can easily pull readable data into a format they can save/sort/etc.
