If you set URLs in this policy, files will only automatically open by policy if the URL is part of this set and the file type is listed in 'AutoOpenFileTypes'. If either condition is false, the download won't automatically open by policy.
If you don't set this policy, all downloads where the file type is in 'AutoOpenFileTypes' will automatically open.
A URL pattern has to be formatted according to https://go.microsoft.com/fwlink/?linkid=2095322.
