Note that a link to a domain that is not specified in the whitelist will end up being recognized as an external site, an intermediate page will be inserted, and the link will be displayed in an external browser outside of the application.

Although it will not be used in the tutorial, add the provisional domain to the whitelist at this time.

Normally, when gadget.xml is parsed, the start URL information is displayed as follows.
