What to do when a scammer is requesting money otherwise they will leak my nudes?

I was chatting with this random girl I met online a little too long ago and she told me to send her nude and I wast thinking that but then sent her. The following morning she had a snapshot of me. And the nudes with my social media, and my number. She told me I would send it all to your followers and your friends unless you will send me the money.
The first one she charged me $50 and then 50 more. Then she requested I should send her 300 dollars to have everything removed off their phone.
