Hi! I am having trouble understanding how to download the amazon_es plugin for logstash. Current documentation says that we should be able to install with the command '/bin/logstash install logstash-output-amazone_es'. My problem is that there is there is no command 'install' ("ERROR: Unknown command 'install') or even a 'logstash-output' that is recognized when I try to execute. This may be a simple fix - please let me know, and thank you!
Logstash version - 6.4.0
