I'm currently following a course on udemy called Microservices with Node JS and React from Stephen Grider, and I've come to a part where I need to run a command:

kubectl expose deployment ingress-nginx-controller --target-port=80 --type=NodePort -n kube-system

And this command is producing this error:

Error from server (NotFound): deployments.apps "ingress-nginx-controller" not found

when I run the command kubectl get deployments I do not see an ingress-nginx-controller deployment so I tried kubectl get namespace and I saw then entry ingress-nginx from that so I then tried kubectl get deployments -n ingress-nginx and then I finally see ingress-nginx-controller from output of that command. So I now know where the ingress-nginx-controller is but I am still pretty clueless as to how i get the initial command of kubectl explose deployment ingress-nginx-controller --target-port=80 --type=NodePort -n kube-system to work i've been stuck on this for a long time now any help is appreciated, thanks.

Edit 1: this is probably not relevant but I also tried putting ingress-nginx after the -n instead of kube-system and it did not work

Also I am using minikube on ubuntu

Edit 2: this is a screenshot of what the course wants me to do because I'm running minikube
