Implementing Exponential Backoff Retry in TypeScript

How to do retry with exponential backoff? I'm currently writing his

Effect.retry(Schedule.addDelay(Schedule.recurs(3), () => '2000 millis')),

Effect.retry(Schedule.addDelay(Schedule.recurs(3), () => '2000 millis')),

How can I make this exponential?
I tried

Schedule.exponential("10 millis")

Schedule.exponential("10 millis")

, but the type signatures don't seem to match
