Convert Object.values([ ... ])to typescript

Question

I am transforming my JavaScript Component to typeScript.

I am facing problem in converting the following propTypes.

Skeleton.propTypes = {
 size: PropTypes.oneOf(
    Object.values([
      ...SKELETON_ALLOWED_SIZES.RECTANGLE,
      ...SKELETON_ALLOWED_SIZES.CIRCLE,
      ...SKELETON_ALLOWED_SIZES.TEXT
    ])
  ),
};

Typescript:

interface SkeletonProps{
    size?:(??)
}
