Changing the cabin air filter in the ventilation system

Where do I access the “Cabin air filter” for the incoming air to the interior of my vehicle? The owners manual says to replace this item every 10K miles on my 2006 Azera?

Open the glove box. Reach inside the glovebox and depress the stoppers on each side. Disconnect the damper on the side of the glovebox. Let the glovebox hang down and you’ll see cabin air filter. Push up on the clips and remove the old filter noting the direction the arrow points on the filter. Install the new filter with arrow pointing in the same direction.
