How to use the cross-domain-utils/src.getDistanceFromTop function in cross-domain-utils

if (domain === getDomain(window)) {
            const global = getGlobal(window);
            global.windows = global.windows || {};
            global.windows[uid] = window;
            this.clean.register(() => {
                delete global.windows[uid];
            });
    
            return { type: WINDOW_REFERENCES.GLOBAL, uid };
        }

        if (context === CONTEXT.POPUP) {
            return { type: WINDOW_REFERENCES.OPENER };
        }

        return { type: WINDOW_REFERENCES.PARENT, distance: getDistanceFromTop(window) };
    }

return { type: WINDOW_REFERENCES.GLOBAL, uid };
        }

        if (target !== window) {
            throw new Error(`Can not currently create window reference for different target with a different domain`);
        }

        if (context === CONTEXT.POPUP) {
            return { type: WINDOW_REFERENCES.OPENER };
        }

        if (isTop(window)) {
            return { type: WINDOW_REFERENCES.TOP };
        }

        return { type: WINDOW_REFERENCES.PARENT, distance: getDistanceFromTop(window) };
    }

return { type: WINDOW_REFERENCES.GLOBAL, uid: uid };
        }

        if (target !== window) {
            throw new Error('Can not currently create window reference for different target with a different domain');
        }

        if (context === CONTEXT.POPUP) {
            return { type: WINDOW_REFERENCES.OPENER };
        }

        if (isTop(window)) {
            return { type: WINDOW_REFERENCES.TOP };
        }

        return { type: WINDOW_REFERENCES.PARENT, distance: getDistanceFromTop(window) };
    };
