'window is not defined' error when including the diffusion core module

[ODonnellBBC]

We're getting the following error when attemping to use Diffuse on an upcoming project. I'm assuming this may be 'commonjs' / 'ESNext' module related?

I'm assuming you're attempting to run it in node correct? Core is only supported in browser environments

and if you are using it in client and stll getting this error ( especially in nextjs) just use "use client"; should fixed this
