NoSuchMethodError: method not found: '__tcfapi' (self.__tcfapi is not a function)

[wszak]

Is any extra setup necessary in the Web version of this package? Some extra js library?
It works fine on Android and IOS, but in the Web version I'm getting this error:

NoSuchMethodError: method not found: '__tcfapi' (self.__tcfapi is not a function)

It's happening in the onListen function:

    _iabtcf_consent_info_web$_onListen$0() {
      self.__tcfapi("addEventListener", 2, A.allowInterop(this.get$_iabtcf_consent_info_web$_listener()));
    },
