create Browser
open override fun createBrowser(url: String, position: BrowserViewport = BrowserViewport.FULLSCREEN, settings: BrowserSettings = ScreenManager.browserSettings, priority: Short = 0, incognito: Boolean = false, inputAcceptor: InputAcceptor? = null): ExternalSystemBrowser
Parameters
incognito
Whether the browser gets cookies and storage of its own that are kept in memory only, instead of sharing the ones the client persists. Not every backend can honour this - check Browser.isIncognito when it matters.
