I have column timezone in my brands table.I want to make timezone dynamic such as which brand is there that time zone should be applied.

public function handle($request, Closure $next)
    {

        $user = Auth::user();

        $brandId = Auth::check() ? Auth::user()->brand : null;

        // Fetch the brand
        $brand = Brand::find($brandId); // You need to replace $brandId with the actual brand ID

        // Set the timezone
        if ($brand) {
            Config::set('app.timezone', $brand->timezone);
        } 
} 

I add this in my AdminAccess.php middleware but it is not storing exact timezone
