Setting the policy lets you set a list of URL patterns that can use Tab Capture. Leaving the policy unset means that sites will not be considered for an override at this level of capture. Note that windowed Chrome Apps will still be allowed to be captured. This policy is not considered if a site matches a URL pattern in the SameOriginTabCaptureAllowedByOrigins policy. If a site matches a URL pattern in this policy, the following policies will not be considered: WindowCaptureAllowedByOrigins, ScreenCaptureAllowedByOrigins, ScreenCaptureAllowed. For detailed information on valid url patterns, please see https://cloud.google.com/docs/chrome-enterprise/policies/url-patterns. This policy only matches based on origin, so any path in the URL pattern is ignored. Example value: https://www.example.com [*.]example.edu
