func upload(files: [URL]) async throws -> Bool {
    try await withThrowingTaskGroup(of: Bool.self) { group in
        let session = try SSH(host: "xxx", port:"xxx")
        let sftp = try session.openSftp()
        
        for file in files {
            group.addTask {
                try await self.upload(file: file, with: sftp, session: session)
            }
        }
        
        var count = 0
        for try await isSuccessful in group where isSuccessful {
            count += 1
        }
        
        return count == files.count
    }
}
