User Profile

I have an application with chat feature. In this, the user is able to attach a document using the app for which I am using UIDocumentPickerViewController. But I read that it requires iCloud capability to be enabled along with an iCloud Container. The app does not create any document on iCloud, but just provides an option to attach and existing document along with a chat message. I want to know whether enabling iCloud is really needed for this use case. Also, the app does not require the document to be on iCloud, it is fine even if the app is able to access only local documents. I did read here: https://stackoverflow.com/questions/37296929/implement-document-picker-in-swift-ios/65917880 that iOS 14 does not require any capabilities but could not find any official document to support this claim.
