createjs.min.js - can I reduce the file size?

Hey all - brand new to Animate and I'm trying to export some banners for Google Ads that have to come in under 150Kb.

I've managed to get all the file sizes down apart from a file located at libs/1.0.0/createjs.min.js which comes in at 242Kb

Is there a way to reduce this file size at all - I've no idea what it actually does so I don't know what I do when I'm working on the file that effects it.

Cheers 🙂
