cloudflared: command not found in Ubuntu

I have been trying to create a Cloudflare Tunnel with cloudflared on Ubuntu (WSL). I followed the link redirected from here and these are what I did:

echo 'deb http://pkg.cloudflare.com/ focal main' |
> sudo tee /etc/apt/sources.list.d/cloudflare-main.list
deb http://pkg.cloudflare.com/ focal main   <---- result of running above command.

Imported GPG key

curl -C - https://pkg.cloudflare.com/pubkey.gpg | sudo apt-key add -

OK  <---- result from running above command.

Before that I had updated repository GPG key with:

curl -C - https://pkg.cloudflare.com/pubkey.gpg | sudo apt-key add -

and

sudo apt-key del 8e5f9a5d

And finally:

sudo apt-get update

However, when I hit cloudflared update command, it returns cloudflared: command not found prompt. Any feedbacks and suggestions would be highly appreciated on where I could have gone wrong.

cloudflared needs to be installed.

You probably added its source but didn't install it yet.

As a matter of fact, run the following command to install it:

~$ sudo apt-get install cloudflared
