Minimum working example for issue described in https://support.google.com/webmasters/thread/171071268?hl=en

• Requires installation of Node.js

• Put these files into a directory, run npm install to install dependencies

• Use ssh -R 80:localhost:8080 localhost.run to setup a temporary tunnel to your local machine, leave that shell open

• Copy & paste the publicly accessible tunnel url that will be established, e.g. https://XXX.lhrtunnel.link

• Open Google Search Console and create a new URL prefix property with that tunnel link

• Use the meta tag verification method and paste it into the project's index.html file's header
