Auth::user on Laravel with different table

Question

I have two additional column for login with different tables. So, I used 3 tables for login with output like this:

When I want to use username its simply write it like this {{ Auth::user()->username }} so I get value KASIR WEB. But it not work with kd_lokasi and kd_shift. Where I should register it? Or how I can get kd_lokasi and kd_shift value and paste it on view? Thank you for helping me.

Table :

    $kd_lokasi = DB::table("tb_kasir_lokasi")->where("vTampil", 1)->get()
        ->pluck("nm_lokasi", "kd_lokasi");

    $kd_shift = DB::table("tb_kasir_shift")->where("vTampil", 1)->get()
        ->pluck("nm_shift", "kd_shift");
