YouTube and visa— help?

Hey, so I’m aware that if I want to do any side work, I need to get a 資格外活動許可. I’m currently here on an instructor visa:

But I also read that creative works are exempt from this, so long as it’s under a certain amount of money? Anyone who has advice or experience would be appreciated.

Just want to make sure I’m not breaking the law when I monetize my channel.
