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

async openBrowser (browserId, pageUrl, browserName) {
        const args  = browserName.split(' ');
        const alias = args.shift();

        const browserInfo    = await browserTools.getBrowserInfo(alias);
        const openParameters = Object.assign({}, browserInfo);

        if (args.length)
            openParameters.cmd = args.join(' ') + (openParameters.cmd ? ' ' + openParameters.cmd : '');

        await browserTools.open(openParameters, pageUrl);
    },

        const openBrowserOperation = () => browserTools.open(...openArgs);

async openBrowser (browserId, pageUrl, browserName) {
        const openParameters = await this._handleString(browserName) || await this._handleJSON(browserName);

        if (!openParameters)
            throw new Error('The specified browser name is not valid!');

        await browserTools.open(openParameters, pageUrl);
    },
