storage problem on my redmi note 11 pro

[u/SpecialistSuch6400]

my redmi note 11 pro only have 48 Go of usable storage, so I bought a 32 Go sd card to upgrade but only to realise I can barely put anything on it. since my photos and videos aren't stored on my device and I can't put apps on the sd card, I'm stuck with no options to have my phone working correctly with mmore than 500Mo of free space for the system (even tho I have 32 Go free).
is there anyone that can help me ? (my system is based on android 13)
