fix: import response type

[TimoGlastra]

Imports the response type, as the ResponseType from DOM was used (which isn't availalbe in AFJ and thus type check throws an error)

[TimoGlastra]

In general there's some DOM types used, which we don't have enabled in AFJ (to stay fully platform agnostic) and that is causing type issues:
