The Teensy 3.2 is no longer available.

Thank you for your excellent work on this. As the 3.2 is no longer in production are there any plans to update the code to work with a 4.0?

Here here. I would like to use this firmware as well. Could it possibly be flashed as it to the Teensy4?

......... as is

No. I believe It makes calls that are specific to the 3.2 so it will not compile for a 4.0. I don't know enough about code or the relevant chips to modify it to work.
