How to switch windows in Winium?

Question

Automation

Good afternoon!
I use for testing a desktop application (thick client) a library - Winium. I'm trying to switch to another window using the following code, but it doesn't work:

window =  driverWinium.findElementByClassName("TNavigatorForm");
        
        WebElement newWindow =  driverWinium.findElement(By.className("TNavigatorForm"));
        String newWindowHandle = newWindow.getAttribute("NativeWindowHandle");
        driverWinium.switchTo().window(newWindowHandle);

        window.click();

What could be wrong?
