Using the checkout Worktree and Create Worktree feature

[Askath]

Hey there :)
Really love this plugin, really love magit and seeing how neogit evolve really makes me happy.
However I have been working with git work trees for a while and saw that neogit also has some mappings for it.

But I am not sure how to use them. For example I want to check out a new worktree. I press ww to checkout a branch, press enter and then I get asked "Checkout in a new Worktree > and a list of folders but I see no way to submit.
Pretty sure I am missing something obvious.
Hope someone can help
