External JS library in Animate?

Hello,

First of all, sorry if the subjetc has already been discussed, but I did not find what I was looking for.

We (in my company) used to create HTML5 interactive creatives in Edge Animate CC, embedding an external JS library that made a bridge between the creative and our own SDK.
With this application not really being supported by Adobe, we turned our eye on Animate, which would seem to fit our creative needs... however, we fail to see how we can still use our library (or a library if we have to apply changes to it) in it.

Anyone to tell me if that's possible and redirect me to documentation that could help?

Thanks a lot!
