I outright tell team members and managers that my camera will not be on unless I am the focal point of the meeting, i.e. I'm presenting. I also don't generally go into meeting rooms anymore, even if I'm in the office. Instead, I call in from my desk or a "phone booth".

I'm also pretty honest about the reason. I have always had trouble looking "engaged" and it's been an issue in many parts of my life. I always fidgeted or doodled in class, but it's how I learn. During the pandemic, I got used to not having to try so hard to look like I'm paying attention. I'm never going back.
