In the page template, add an element to the page that links to the tool on ToolHub. The name of the tool is accessible using {{ tool.name }}
The string used for the link should be a translatable message. To do this, add the message to qqq.json and en.json in the i18n folder. Then you can use the message in the template using {{ msg('your-message-name') }}
You can use Bootstrap UI elements to style the link.
