Yes, you can use HTML to add a hyperlink to open a URL. This can be done in a tour or game and in any template where there is a text field or input field for HTML.
To embed a link into a project, it may take this form:
<a href=”https://example.com/”>Example</a>
In this case, “example.com” is the website you want to link to and “Example” is the title you want to display as the link.
