My company was part of an early pilot using Virtual Sapiens. We went through their certification process. You take an assessment and then view videos in their learning lab to improve your presence. You can continue taking assessments until you pass the virtual presence tests. Once done, you get a certificate you can share on LinkedIn. After that we started using Sidekick Coach on our Zoom and Google Meets. Totally private, nobody knows you are using it and your data stays on your device only. I have ADHD and found it helps me stay focused when I'm on a call. The Sidekick Coach also reminds me of my video meetings for the day and just helps me organize a little better. I recommend it.
