🔎 Spotlight Search Problem 🔍

I'm having difficulties searching for apps that came with my Mac through Spotlight Search. Whenever I open Spotlight, I can search for all the apps that I installed like Whatsapp and Office, but all the other Mac apps like Terminal, Activity Monitor, Maps, FaceTime, Calculator, App Store, etc don't show up on Spotlight... except for Safari.

Also it doesn't show weather reports, sports team reports, and other Siri related functionalities.

Also, all the items in "System Preferences > Spotlight > Search Results" are checked!

I also tried unchecking them all and rechecked them again.

I'm using M1 Macbook Pro on MacOS 12.4

I've had this problem for months now.
