Remote unlocking rear seats boot missing

Good evening to everyone, I’m new here in the forum, but I’ve been reading with you for a while. Today I got my new Tarraco xcellence. 200 hp diesel engine as 5 seaters. Now my question: I assumed that I can unlock the back seats by a lever in the trunk. With my car these levers are missing. Is that normal? On all pictures and videos I see these parts, also my previous Alteca and Kodiaq have these. Is that also so with you? Thank you for your help.
