Someone writes that he hacked into my phone and also the camera

An unknown user with the mail Email@mb38.com writes to me that I was hacked with the help of the pegasus program and says he will do something to me and post videos in which I do something strange, although this has never happened, most likely even if he sends something, it will be an AI-generated video with my face. But I want to make sure that no one has hacked me and manages my phone and information
