Problem in https://auth0.com/blog/complete-guide-to-react-user-authentication/

In https://auth0.com/blog/complete-guide-to-react-user-authentication/, the instruction 

```
$ git clone -b starter git@github.com:auth0-blog/auth0-react-sample.git
```

Happens to not work for me on Ubuntu 20.04. Instead,

```
$ git clone -b starter https://github.com/auth0-blog/auth0-react-sample.git
```

does work.
