Telescope list files in decending order

I am trying to get a listing of my journal entries in descending order. I create a file for each day named with the date as follows:

I am using the Telescopes builtin find_files as follows:

    cwd = journal_dir;

This however lists the oldest files first. I want it to be in the opposite order. I have tried setting sorting_strategy to ascending. but that just moves the first selection to be at the top.
