clicknium can't identify windows pop-up window?

[phoenixor]

I need to automatically operate the pop-up window of Windows desktop software in the crawler, in the middle of the pop-up window is a list of users, below is the confirm and cancel buttons, I need to identify the pop-up pop-up window, then click the specified user in the user list, and finally confirm. The pop-up title was selected using clicknium's selector, and the user in the list could recognize it with the "validate" button, but the pop-up content was not recognized when the code ran until this time, and tried to change to IA or image recognition technology, but it had no effect
