Authentification failed [closed]

I develop in Laravel and I need to do authentication with two roles but it does not work : if the role of the user is a technician or engineer the system must go to the homet.blade.php page ,

here the code is what the syntax is just :

@if (Auth::user()->role == "Technician" xor Auth::user()->role == "Engineer" )

window.location = "/homet";

@endif

I tried to insert the logical operation "xor" but it does not work
