Typescript: Allow Frames to be undefined on Window

[ChrisSargent]

Wouldn't it be more accurate for the Frames type on Window to be like this?

declare global {
    interface Window {
        Frames: FramesAppendedProps | undefined;
    }
}

frames-react/src/frames/Frames.tsx

Line 8 in 282a325

Frames: FramesAppendedProps;
