Ah, you are right it is still in Beta. That's why the new tabs don't appear. This is the tutorial- https://www.youtube.com/watch?v=VsLjVVs7SX4 She does mention that actually. I just missed it (the video is from October 2020 so I just assumed it was in the latest version).
I'm not sure if I want to install a Beta in the midst of an important project. I will continue to use Youtube's auto translate for now.
