Custom submit button component for SearchField

[ScyDev]

In the code of SearchField.js I see this:

  /**
   * The component to use for the submit button.
   */
  SubmitButtonComponent: _propTypes["default"].elementType,

Does this mean we can pass our own custom component to be used for the submit button?

I tried this, but didn't work:

          <SearchHeader>
            <SearchField onChange={value => updateSearchTerm(value)} value={query} SubmitButtonComponent={CustomSearchButton} >
          </SearchHeader>
