Who is the youngest girl billionaire?

Could you please clarify for me who exactly holds the title of the youngest female billionaire in the world? Is there a specific individual who has recently gained this distinction, or has there been a notable change in the ranking of young female billionaires recently? Additionally, what industry or field does this individual operate in, and what are some of the key factors that have contributed to their success and rapid accumulation of wealth? I'm particularly interested in understanding the unique challenges and opportunities that come with being a young female billionaire in today's global economic landscape.
