Smartcard login will hang with the unknown popup

Any idea how to automate this smartcard login process?
It will just hang after clicking on the SmartCard_Login button when the popup appears
WebUI. click ( findTestObject (‘SmartCard_Login’))

what kind of popup is this?
how to handle the popup?

Currently my workaround is to click on the image of the SmartCard_Login button, but is there a better way?

seems to me like windows native window … look at

i’m using it to login into PowerBI app that’s configured for windows sso (throws native windows login window too)

thanks. that’s exactly my another workaround for the problem. I use Robot to keypress TABs and Enters, with Clipbroad to achieve it.
