Session Expired Time

Hi everyone. I want to show user auto logout time (session expired time). How can I access user session. This is my login controller:

            'systemUserName' => ['required'],
            'password' => ['required'],
        ]);
 
        if (Auth::attempt($credentials)) {
            $request->session()->regenerate();
 
            return redirect()->intended('/users');
        }
 
        return back()->withErrors([
            'email' => 'The provided credentials do not match our records.',
        ]);
