The Ansible AWX project has an official open source CLI toolkit which you should use instead:
https://github.com/ansible/awx/blob/devel/INSTALL.md#installing-the-awx-cli
tower-cli is a legacy command line tool for Ansible Tower.
It is also what the Ansible tower_* modules use under the hood. Such as:
https://docs.ansible.com/ansible/latest/modules/tower_organization_module.html
These modules are now vendored as part of the AWX collection at:
https://galaxy.ansible.com/awx/awx
Supporting correct operation of the modules is the maintenance aim of this package.
