This is no different when using Hooks. You specify the type of props as the type of the first argument in the functional component:

  function MyComponent(props: IMyComponentProps) { ... }

Where the type definition of IMyComponentProps resides doesn't matter, you can import it from anywhere.

I was simply pointing out that explicitly defining an interface is not necessarily a downside.
