Subject: [PATCH] =?UTF-8?q?=E2=9C=A8=20feat:=20add=20new=20route=20to=20ge?=
 =?UTF-8?q?t=20client=20callback?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This new route serves to find the client callback after successfully logging in from the provider page. This is done so that the callback becomes more flexible and can be changed at any time.
