ADB can't find my s20 ultra even with developer mode enabled on mac

Hey,
So I've decided to go to the next level with my little android toy. I've already gotten ADB for mac (the bear minimum, not android studio) from here.
https://developer.android.com/tools/adb
and have enabled developer mode on my s20 ultra by tapping about 7 times on the build number under about --> software.
When I write adb devices in terminal, I don't get any result.
I previously tried to just access the file system, on google everyone say that I should be getting a notification to give permission from my s20 ultra but I don't get anything so maybe the problem is there.
Thanks in advance, I am sure it's a very obvious mistake I'm making, and I am very very novice with Android in the first place.

Have you by chance turned on usb debugging in the phone's developer options? It's not on by default.

Wait, so after dev mode is on I have to enable that option or is it automatically enabled when developer mode is on?

You have to manually enable it in your phone's developer options even after you turn on dev mode. I think they do this for security reasons.
