What can my cousin do to get back a visitor visa?

Good Afternoon Mrs. Huntington,I hope this email finds you well. I am desperately seeking guidance on how to navigate next steps for my cousin's B1 visa that was recently denied. She overstayed five months due to her mother’s passing in the Bahamas. We were trying to figure things through, but ensured that she went back before the six months in good faith hoping it would have been renewed.
