Setting the policy lets you list the URL patterns that specify which sites can ask users to grant them access to a HID device.
Leaving the policy unset means DefaultWebHidGuardSetting applies for all sites, if it's set. If not, users' personal settings apply.
For URL patterns which do not match the policy, the following take precedence, in this order:
* WebHidBlockedForUrls (if there is a match),
* DefaultWebHidGuardSetting (if set), or
* Users' personal settings.
URL patterns must not conflict with WebHidBlockedForUrls. Neither policy takes precedence if a URL matches with both.
For detailed information on valid url patterns, please see https://cloud.google.com/docs/chrome-enterprise/policies/url-patterns. * is not an accepted value for this policy.
