you could reply back and tell her something like this:
"I'm OK with you not being there and your friend being there but I don't need her asking me about every item that I'm taking. Also I don't want to hear any complaints that I went searching in a room where I shouldn't have been or that I took something I shouldn't have taken because I really don't want to put up with any nonsense while I'm taking my stuff out of the apartment. Plus I don't want to waste my time if I can't find something of mine and I have to make 2 trips, I'd rather do this in one trip and not have to come back again. I've made myself clear on all of this now so I don't want to hear about any problems afterwards."
or you could say:
"you should probably be there, if I can't find something that I'm looking for I don't think your friend will be able to find it, you'll be able to see what I'm taking so there's no issues with me taking something that I shouldn't have or some other nonsense, I want to do this in one trip without having to come back because something was missing or hidden."
In the end bro, it's up to you. Do what's best for you.
