 You should handle validation in a form request. On the form request you should use the `Spatie\MediaLibraryPro\Rules\Concerns\ValidatesMedia` trait. This will give you access to the `validateSingleMedia` and `validateMultipleMedia` methods.

-After you've validated the response, you should persist the changes to the media library. The media library provides two methods for that: `syncFromMediaLibraryRequest` and `addFromMediaLibraryRequest`. Both these methods are available on all [models that handle media](/docs/laravel-medialibrary/v10/basic-usage/preparing-your-model). Either way call the method `toMediaCollection` to update your media-model in the database. This will also ensure that temporary uploads are converted to the appropriate model.

 You should probably use this method when only accepting new uploads.
