Welcome here, where people help and actually can help each other gladly! You’ll need those two packages:
firmware-misc-nonfree
firmware-iwlwifi
By using of sudo dpkg -i after downloading:
https://packages.debian.org/bookworm/firmware-misc-nonfree
https://packages.debian.org/bookworm/firmware-iwlwifi
In addition, both @knurtsj and you might take advantage of using isenkram-autoinstall-firmware method, as described in this thread/post: Wifi on MacBook - #61 by Quarnero.
