Add the following function to your Common.js or User.js file, so it is accessible in your test cases.

function ConnectBrowser(/**string*/ profileName)
{
	var profileFileName = profileName + " Session.json";
	if (File.Exists(profileFileName))
	{
		File.Copy(profileFileName, WebDriver.webDriverSessionFileName)
	}
	else
	{
		File.Delete(WebDriver.webDriverSessionFileName);
	}
	Navigator.SelectBrowserProfile(profileName);
	var sessionId = WebDriver.ReconnectSession(true);
	Tester.Assert("Connected to " + profileName, sessionId != null);
	if (sessionId)
	{
		WebDriver.SaveSession();
		File.Copy(WebDriver.webDriverSessionFileName, profileFileName)
	}
}

Create and configure local browser profiles, for example "Selenium - Chrome 1" and "Selenium - Chrome 2".

Switch between browsers in your test like this:

ConnectBrowser("Selenium - Chrome 1");
WebDriver.SetUrl("https://v3.libraryinformationsystem.org/reactui/");

ConnectBrowser("Selenium - Chrome 2");
WebDriver.SetUrl("https://v3.libraryinformationsystem.org/angularui/");

ConnectBrowser("Selenium - Chrome 1");
var usernameField = WebDriver.FindElementByXPath("//input[@id='username']");
usernameField.Click();  

ConnectBrowser("Selenium - Chrome 2");
var usernameField = WebDriver.FindElementByXPath("//input[@id='username']");
usernameField.Click();
