Testing Angular and Primeng p-confirmPopup

[tecob1234]

Attempting to test the Yes option on a Primeng p-confirmPopup. When finding and clicking the Yes button, I receive many errors such as TypeError: Cannot read properties of null (reading 'icon'). How do I pass the object that is expected when the Yes button is selected?

confirmationService.confirm({ target: event.target, message: 'Are you sure that you would like to remove this ?', icon: 'pi pi-exclamation-triangle', accept: () => { .....

Thanks in advance
