Maxi-Cosi Zelia Luxe Cleaning[sk]

Hi! I have the Maxi-Cosi Zelia Luxe 5-in-1 Modular Travel System and for the life of me I can’t figure out how to take apart the car seat to clean it. My child make a massive mess in it and I wanted to take it apart to wash it but can’t find any videos on it or anything. Does anyone know how??

Thanks!
