Hello
In the middle of the process, when you click a button on the current chrome page (application), a new window opens. (Web page - chrome ) It is necessary to click a button in this newly opened window. When you get the XPath of this button, it leaves the first application because it is a new window, and therefore the button not found error is received in the flow.
To attach to the newly opened window, you need to switch to the frame that occurs in between using the “Applications - Switch actions” component.
