Hi guys, can we have one more approver here? It's a simple change, won't take long to review.

@micksatana Looks like we need to fix one of the tests to account for the added type

Hi @micksatana - thank you for this contribution! We are currently working on improving our TS types, including adding support for typing the configure function. You can check out our RFC proposal here
