To enforce google safe search for a particular user only on microsoft edge browser and not on any other browser.

hello there,
i want to create a policy in safesquid which will enforce google safe search for a particular user only for microsoft edge and not on any other browser.
the google safe search should be disabled for any other browser except microsoft edge for that user.
please provide me instructions on it.
