Converting AsyncIterableIterator to Array within Effect Type

// This is what I want:
// readDirEffect(path: string): Effect.Effect<Promise<(FileSystemDirectoryHandle | FileSystemFileHandle)[]>, SomeError> {
// This is what I'm currently getting
readDirEffect(path: string): Effect.Effect<(FileSystemDirectoryHandle | FileSystemFileHandle)[], SomeError> {
    return pipe(
        getData(), // This returns something like Effect.Effect<AsyncIterableIterator, SomeError, never>
        Effect.map(a => asyncIterToArr(a)),
    );
}
