Use a Javascript Library in ExecuteScript_Sandbox

I’m trying to let UI.Vision send me an SMS notification once a certain daily job is done. I aim to use Twilio API to achieve this goal. But, to use this API, it requires to install a javascript helper library. Is it possible to install a javascript library in ExecuteScript_Sandbox? Or install a library in the local storage of the browser so ExecuteScript can run commands from this library? Thanks
