I am using the public disk

Good afternoon, please if you can help me, I am using the package and I save the data like this

$post->{'post-trixFields'} = $request->input('post-trixFields');
$post->{'attachment-post-trixFields'} = $request->input('attachment-post-trixFields');

how can I tell it to save it in a specific directory, for example: blog/images, it is currently saving me in the root of the storage, the ide and do not modify the package. thank you so much
