Need help with enabling camera on V2 on Raspberry Pi 4 Model B

I'm completely new to anything raspberry pi related and I started a school project with it. Here's a list of all the parts I've got from amazon: Raspberry Pi 4: https://www.amazon.com/Raspberry-Model-2019-Quad-Bluetooth/dp/B07TD42S27/ref=as_li_ss_tl?dchild=1&sr=8-4&linkId=b48356bc3c6888cd7c44fd1130081d1a&language=en_US Raspberry Pi Camera Module V2-8: https://www.amazon.com/dp/B01ER2SKFS?psc=1&ref=ppx_yo2ov_dt_b_product_details Touch Display: https://www.amazon.com/dp/B09XKC53NH?psc=1&ref=ppx_yo2ov_dt_b_product_details and ofc everything else like SD cards, display cables, etc. I tried following this tutorial I found on Youtube: https://smartbuilds.io/smart-cctv-camera-flask-video-streaming-opencv-raspberry-pi/ One of the first steps is to 'Select Interface Options, Camera Port and select Enabled. You can now exit. This may cause your Pi to reboot." but no camera port option is showing up in the raspberry pi config. Any ideas? I've looked at countless articles and videos, but nothing seems to work.

It shows that no cameras are avaliable when I run "libcamera-still --list-cameras" when I have the camera module connected correctly

you don't need to enable it now

you used to have to in the old os but not anymore
