unable to install apache-airflow-providers-sftp==4.1.0 on MWAA 2.4.3

hello, i am trying to install the apache-airflow-providers-sftp==4.1.0 package on our MWAA 2.4.3 with private network access. I download the wheels for all the packages in my requirements.txt file and put them in plugins.zip and then upload to s3 and provided the path to this plugins.zip in the requirements.txt file. Other dependencies like kubernetes or presto are getting installed fine but apache-airflow-providers-sftp is throwing an error:

ERROR: Could not find a version that satisfies the requirement bcrypt>=3.2 (from paramiko) (from versions: none) ERROR: Could not find a version that satisfies the requirement pynacl>=1.5 (from paramiko) (from versions: none)

these errors are from scheduler logs.

here are the relevant .whl file version i have in my plugins.zip:

apache_airflow_providers_sftp-4.1.0-py3-none-any.whl apache_airflow_providers_ssh-3.4.0-py3-none-any.whl bcrypt-4.0.1-cp36-abi3-macosx_10_10_universal2.whl PyNaCl-1.5.0-cp36-abi3-macosx_10_10_universal2.whl

Thanks
