When introducing a new toy, you can leave it close to her cage for a couple of days, then hang it on the outside of her cage a couple more days, before taking it inside. You could also play with the toy while she looks, she should be curious about it and want to try it. I have 3 birds, 2 untamed, and when I give them a new toys while they are out, it takes them ages to fly back in, anything new is very scary. My third bird is tame and he couldn't care less, everything is fine to him.
With my 2 untamed birds, we have some rules. When I first got birds, I had no clue and they had almost never been out of their cage. The lady who had them tried it twice and it took so long to get them back inside that she didn't let them out after that... She had bought them from a shop so basically they had been flying twice in their lives and it was a whole new experience for them, they didn't find back to the cage door and wouldn't let me approach them to help. I spent a good couple hours to get them back in.
So I tried presenting them with a perch, they stepped up on it and after many tries, I managed to carry them back to the cage (of course, they were two so once one was in there, I would have to fetch the other one but leave the door open so he would be able to go inside without freaking out when I opened the door, but then of course, the other one was able to fly out if it took too long to get the second one in.. Luckily you won't have that problem! They learned to climb on the perch and go back to their cage like that. Not working 100%, sometimes I had to go and pick them up again and again because they would fly away, but once I had started, I wouldn't not give up until they were both in the cage. If you let your bird learn that there is a way to do what they want, they'll make your life impossible. If they are asked to step up and go back inside, they HAVE to do it, no matter how long it takes!
However, I could never get them in another cage with that method. Not because they are bad birds, but because they are scared of anything different. So I made them a bus. Which is basically a home-made box of bird-net, with 2 perches inside, which I use to transport them from one place to the other, be it another cage or the shower.
I put it in front of their open door, gently chase them toward it, they know the drill and jump in. I turn the opening from the door to my belly so it remains closed, and I turn it against the next door so they jump out and in the new place.
