emptyMessage doesn't supports ()=>JSX.Element

[jgarmar]

Describe the bug
Example isn't working in a TSX file:

<SelectSearch
  options={options}
  search
  filterOptions={fuzzySearch}
  emptyMessage={() => (
    <div style={{ textAlign: "center", fontSize: "0.8em" }}>
      Not found renderer
    </div>
  )}
  placeholder="Select your country"
/>

TypeScript says that Type '() => JSX.Element' cannot be assigned to type 'string | (() => string) | undefined'

It would also be interesting if some action could be carried out with that query, for example creating it.
