Thanks @weizhouapache. Currently, local upload is not supported. Also, for local upload, do you mean uploading the manifest YAML from local machine or the complete extension source?
Either way, it would first need implementation of allowing upload on the management server (Currently we only upload via SSVM) or we upload to SSVM (secondary store) and then transfer to the management server host
If it is just the YAML then we can follow the same flow - get YAML, parse it, download the extension source and automate the process of adding extension and its actions.
For extension source upload, the operator need to pass extension details like name, description, type, etc.
