What made Sarah Michelle Gellar change her mind?

For years she used to get interviews from various magazines/websites asking her about either returning to Buffy or doing a revival, and she would always say something like, "That part of my life is over now," or "I've moved on, etc."

Now all of a sudden 20 years later she changed her mind? I know she was rewatching the show with her kids during covid, but I wonder if Joss being publically humiliated and exposed had something to do with it.
