How to access window variables

[jxh150535011]

My application will load certain modules that will attempt to access the window.fetch variable (throw an error if the window.fetch variable does not exist).
This will cause the module to throw an exception directly during the "Error while collecting story" phase.
Is there any configuration for me to add polyfill or other troubleshooting methods to prevent this module from executing on the node side for the current issue
