Question No slot for antennas for me to add wifi card to my asrock z270 pro4

[wxlpmnb]

Hey, computer noobie here, trying to add a wifi card and antennas to my motherboard. However, in most tutorials, the computer seems to have these golden little slots for antennas (see image 1, which i've found online). My computer doesn't have these (see image 2, my computer). Does anyone know what I'm supposed to be doing? Am I supposed to be buying something to have these golden slots?

This is the wifi card im planning to buy, these are the antennas.
