How to custom not found message in laravel instead of "No query results for model"

Handler.php

public function render($request, Throwable $exception)
{
    if ($exception instanceof ModelNotFoundException) {
        $model = app($exception->getModel());
        return \response()->json([
            'message' => method_exists($model, 'notFoundMessage') ? $model->notFoundMessage() : 'Resource not found',
        ], 404);
    }

    return parent::render($request, $exception);
}

User.php

public function notFoundMessage()
{
    return 'User not found';
}
