Recover Worlds button is missing in new UI

The new interface they are working on is very cool, the problem is that there is a missing button to add to the new Minecraft beta interface, it is recover world like the button on the old interface that is there.

thank you very much I love your game they are the best.

Steps to Reproduce:

1. Remove all of your worlds from the worlds list
2. Notice the "Recover Worlds" button is there
3. Switch to the new UI
4. Notice the "Recover Worlds" button is no longer there
