import java.util.Arrays;

public class MamimizeBrowser {

    @Test
    public void firstTest() throws InterruptedException {

        Playwright playwright = Playwright.create();
        Browser browser = playwright.chromium().launch(new BrowserType.LaunchOptions()
                .setArgs(Arrays.asList("--start-maximized"))
                .setHeadless(false)); // Set headless to false
        BrowserContext context = browser.newContext(new Browser.NewContextOptions()
                .setViewportSize(null));
        Page page = context.newPage();
        page.navigate("https://blazedemo.com/login");
