How to use the testcafe-browser-tools.isMaximized function in testcafe-browser-tools

private async _resizeLocalBrowserWindow (browserId: string, width: number, height: number, currentWidth: number, currentHeight: number): Promise {
        const resizeCorrections = this._getResizeCorrections(browserId);

        if (resizeCorrections && await browserTools.isMaximized(this._getWindowDescriptor(browserId))) {
            width -= resizeCorrections.width;
            height -= resizeCorrections.height;
        }

        await browserTools.resize(this._getWindowDescriptor(browserId), currentWidth, currentHeight, width, height);
    }

private async _calculateResizeCorrections (browserId: string): Promise {
        if (!this._isBrowserIdle(browserId))
            return;

        const title = await this.plugin.runInitScript(browserId, GET_TITLE_SCRIPT);

        if (!await browserTools.isMaximized(title))
            return;

        const currentSize = await this.plugin.runInitScript(browserId, GET_WINDOW_DIMENSIONS_INFO_SCRIPT);
        const etalonSize  = subtractSizes(currentSize, RESIZE_DIFF_SIZE);

        await browserTools.resize(title, currentSize.width, currentSize.height, etalonSize.width, etalonSize.height);

        let resizedSize    = await this.plugin.runInitScript(browserId, GET_WINDOW_DIMENSIONS_INFO_SCRIPT);
        let correctionSize = subtractSizes(resizedSize, etalonSize);
