So I have nested Traps, both with the prop clickOutsideDeactivates. However when I click outside both traps while the inner one is active only the inner one closes.

Is there a pattern I can use to close both traps if the click is outside of both, or just the inner trap if the click is outside the inner trap but within the outer one?

These new hooks should help with this use case.

The pause/unpause hooks are in focus-trap v7.4.0 and focus-trap-react v10.1.1.
