I want to clone my public repository from Github to my local system using `gh` official cli.

I copied the following command from the repo (green code button) button and also followed the official documentation -

```
sudo gh repo clone <username>/<repo-name>

```

But the repository does not clone, but instead, the command returns the following output on the terminal.

```
Welcome to GitHub CLI!

To authenticate, please run `gh auth login`.

```

I also executed `gh auth login` and logged in. But still, the command returns the same output.

I can clone the same repository using following command

```
git clone "url"

```

I am using Ubuntu 18.04. How can I clone the repository using `gh`.
