How do I add multiple UEs?

Hi, I am not good at English. That is why I use translation tools.
I apologize in advance for any rudeness that may have been expressed.

Multiple UEs were added using web console.What should I add to free5gc-ue.yaml in UERANSIM at this time?

There is no need to make additional modifications to free5gc-ue.ymal.
