Totally doable!

DIY (you have to think more, but you also get to learn more):

• Follow this tutorial but with Tasks as your primary model (instead of Accounts) and Accounts as your model for the drawer (instead of Contacts).


• Have the condition on your Account object be Id = filterable default off.
  


• When the drawer is loaded have it activate and set the value of this account condition to {{{WhatId}}} or {{{AccountId}}} (this will bring in that value from the task row in context.


• For any components in the drawer set to the account model, add a context condition where Id of record = AccountId of row in context.
