Until somebody who has done this comes along, I might throw in some guesswork. It may not be worth much but might turn out, so consider or reject as it fits!
Sometimes seeing a picture can give us a clue of where the little "secret latches are so we can know to look there?

Down about page 94 there are a number of louvers which may be what you have.
You might look to see if you can spot what you have but one I noticed looks like it has a metal retainer and the louver has tabs on the sides which could come down the notches if turned the correct way? Maybe rotate the louver until is drops down and comes free? Does that make any sense?

There are no visible screws on the trim ring must pry off or turn off looking for answer before i break something as usual.
