@Edo-San Hello, quick question which is related to this change.

Why should for example filename in AssetStoryblok always be nullable, even if the Asset is set as required in Storyblok?
Is there a possibility to implement that?
I just changed from the old package to this and the typing for assets was a easier that way.
