Customize laravel sanctum unauthorize response

Question

I am using laravel sanctum in my project, but I am facing a problem. I want to customize the 401 response code (unauthorized) to return a JSON when a token is invalid, something like this:

    {
    "data": {
        "code": 401,
        "book": null,
        "success": false,
        "error": {
            "message": "Not authenticated"
        }
    }
}

Instead of default response:

{
    "message": "Unauthenticated."
}

How to achieve this in laravel sanctum? Thanks in advance.

Rendering exceptions

Add to ExceptionHandler@register app/Exceptions/ExceptionHandler.php

$this->renderable(function (\Illuminate\Auth\AuthenticationException $e, $request) {
    if ($request->is('api/*')) {
        return response()->json([
            'message' => 'Not authenticated'
        ], 401);
    }
});
