+   	chromedp.ExecPath("path/to/chromium-browser"), // Specify the path to Chromium executable
+		chromedp.Flag("headless", headless),         	 // Disable headless mode
+		chromedp.Flag("disable-gpu", headless),      	 // Enable GPU
+		chromedp.Flag("start-maximized", !headless), 	 // Start maximized
+	)
