Hi @mksrqa

`Windows.findElement` do not take in a By argument, only a Test Object. Please capture your object with Window Spy and and then use `findTestObject('your test object id');`

Hi @mksrqa,

In-case you want to findElement by Selenium.By, you can try this:

```auto
Windows.getDriver().findElement(By.id('username'))

```

Thanks

Hi @duyluong  
I don’t understand his "inspect.exe to identify the object " table, I don’t see any ID card. So how to use the method below? Where is the " id " ?  
**Windows.getDriver().findElement(By.id(‘username’))**  
Currently I only use Windows.getDriver().findElementByName(‘Username or email’)

@ngoctamthd  
To inspect an application, you can use Katalon Windows Spy object or Windows’s Inspect.exe.  
The ID of a Windows element is **AutomationId** property.
