How to Query Today's Journay for Done Tasks?

I am trying to create a Task dashboard. When an item is DONE, I’d like to drag & drop it into the journal for today (presummable the day the task was completed). That way, DONE tasks are archved into the journal.

How can I write a query to embed in my Task dashboard to show the current day’s DONE tasks?

This is what I have so far, but it shows all DONE tasks.

{:title [:h2 "Todays Done Tasks"]
 :query [:find (pull ?b [*])
             (task ?b #{"DONE"})
