I’m sorry, I can’t support third-party plugins with osTicket Awesome.
Having said that, I did take a quick look for you and I can say that there is nothing about this plugin that would make it difficult to install. Whether you are installing it with osTicket or osTicket Awesome — the instructions should pretty much be the same.
I have no idea how well it will work with osTicket Awesome though. YMMV. Good luck!
