How do I keep the preview option in the studies, the way it is?

When I was making my studies, I found this feature called preview, Yes , the one with an eye. I found it cool, so I decided to add it in my studies. But when I click on it, and go to another chapter, it does not remain the same. What should I do?

Thank you!

If you install the LiChess Tools browser extension, you get that by default (https://siderite.dev/blog/lichess-tools---user-manual/#stickyPreview), @hiyap

Yay!
Thank you!
But I have installed it....

@hiyap , by default it's on. If you have not turned the feature off, Preview should stay on until you switch it off:

If it doesn't work, contact me privately.
