Azure AD Login and Redirect Based on Group

Is there an Azure service/resource I can use that will authenticate user based on tenant active directory, and based on their group membership, redirect to different URLs? My original thought was to create a .NET app (app service), setup for AAD authentication, read membership, and redirect the user. It seems overkill to setup an application for this so I'm wondering if there's an easier/quicker/more nimble way to do this.
