Replace cabin air filter

2001 Nissan Altima XE.
I removed the glove box (but didn’t do like the video said and pull out the pins first, so now I broke it :angry:)
But… No AIR FILTER! Just a smooth tan curved wall, attached to the dash panel. Do I need to remove this too? All the videos say the CAF should be right there behind a horizontal panel.
Is it because I have an XE?
