     ./us3cli restore us3://bucket/test --parallel 10
     NOTE:

     • Replace bucket with your bucket name.
     • Replace test with the names of files or folders to be restored.
     • --parallel specifies the number of files to be restored concurrently. The default value is 10. You can modify it as needed.
