I'm trying to use the deleteItems call to delete all items in a collection but getting a validation error response from the API.

await this.webflow.collections.items.deleteItems(collectionId)

The documentation and the typescript client say items is optional so I don't understand why this would not be allowed.

API Docs: https://developers.webflow.com/data/reference/cms/collection-items/staged-items/delete-items
Request Type Definition:

Is it possible to bulk delete all items from a collection? And if so, how can this be achieved?
