Plugin is not installed correctly

[vinaypillutla]

I am trying to install a plugin using a python script. I am able to register the extension on the mob. However, I am unable to see the corresponding plugin files on the VCSA (They should be copied to /etc/vmware/vsphere-client/vc-packages/vsphere-client-serenity). As of now, the script sets appropriate values (url for plugin zip file is also set) for vim.Description(), vim.Extension.ClientInfo() and vim.ExtensionServerInfo() and then calls content.extensionManager.RegisterExtension(). Wanted to know if setting these values alone would be enough for the script to download the plugin from the url and place it in the appropriate path, or is there something that I am missing.
