Laravel get storage url with custom subfolders inside storage directory where files are stored

In my Laravel(v5.8.x) project, I have implemented the function of uploading images thro' CKEditor(v4.14.x).

But I want to store and fetch images from storage/wysiwyg/[AnyDir] path.

I have this code with Storage facades included:

public function upload(Request $request)
{
    $destPath = storage_path() . DS . 'wysiwyg' . DS . '[AnyDir]';
    if ($request->hasFile('upload')) {
        $originName = $request->file('upload')->getClientOriginalName();
        $fileName = pathinfo($originName, PATHINFO_FILENAME);
        $extension = $request->file('upload')->getClientOriginalExtension();
        $fileName = $fileName.'_'.time().'.'.$extension;

        $request->file('upload')->move($destPath, $fileName);

        $CKEditorFuncNum = $request->input('CKEditorFuncNum');
        $url = Storage::url($fileName);
        exit($url);
        $msg = 'Image uploaded successfully';
        $response = "<script>window.parent.CKEDITOR.tools.callFunction($CKEditorFuncNum, '$url', '$msg')</script>";

        @header('Content-type: text/html; charset=utf-8');
        echo $response;
    }
}

But the Storage::url method ignores the subfolders wysiwyg and [AnyDir], how do I get full storage url along with subfolders in proper order ?
