The newest version of IntelliJ says it has support for git worktrees, but I can't seem to find anywhere that says how to use it. I was expecting to see an entry in the Git Branches popup in the lower right, but I don't see it there.

I also don't see any descriptions in:

IntelliJ help and googling were also unhelpful

I'm using Git version 2.7.2.0, worktrees were introduced in 2.5
