Instance methods

StorageAccessHandle.getDirectory(): Returns a Promise that fulfills with an unpartitioned FileSystemDirectoryHandle object if access was granted, and rejects otherwise.
StorageAccessHandle.estimate(): Returns a Promise that fulfills with an unpartitioned StorageEstimate object if access was granted, and rejects otherwise.
StorageAccessHandle.createObjectURL(): Returns a string representing the unpartitioned blob storage url created if access was granted, and throws otherwise.
