Using Aspera SDK inside Retool

Hi guys, I am trying to use Aspera to download some content from our backend, via the IBM Aspera connect-sdk-js library.

From what I understand from the docs and other forum conversations, the library should be preloaded and then the contents should be available throughout my app.
Unfortunately, it seems that the library isn't being loaded and I fear it might be a compatibility issue, for example due to the library referencing the parent window object from code.

Could anyone please confirm if this library is indeed incompatible or if a compatible version exists or recommend a workaround?

Here is the repo: GitHub - IBM/aspera-connect-sdk-js: Official Aspera Connect SDK for Javascript
Here is a CDN version:

Thank you very much!
