ExtReact - npm ERR! 403 403 Forbidden

I am trying to use trial version for ExtReact and using link

https://docs.sencha.com/extreact/7.2.0/guides/getting_started/creating_ext_react_app_modern.html

So, successfully got username and password and able to login as well in Step 2.

But when running Step 3: Create a React application with create-react-app and ExtReact template is not working. The below command is giving below error.

npx create-react-app --template @sencha/ext-react-modern ext-react-modern-demo

Error:
