Door threshold help
Hello!
I recently purchased a home that has a sagging exterior door threshold (I think it's a threshold?) when stepped on. I believe this sag caused rotting of the door trim, which is one of the first things I had replaced.
Original issue: rear entry door trim rot

My guess is that there was originally caulking between the trim and threshold, but the caulking was compromised because the entire threshold would move when stepped on.
I had the threshold sagging repaired but I don't think the repair went far enough. The repair person used a 1x3 board (not treated) board underneath the threshold to prop it up. It helped, but there was still sagging. In the video you will see the leftover nails where I pulled

What is the right way to repair the sagging ? Two thougsh:
1.) Place some shims under the threshold ? If so, should they be treated, plastic ?
2.) Take out the sill and replace it with concrete ?
I appreciate any advice!
Thank you,
John
This is a picture of me pressing down on the threshold, along with what I am calling a sill and threshold

This is a picture of the uncompressed threshold.
