In LaTeX I often include my own custom environments via the package tcolorbox. I would like those custom environments to show up in the document symbols, so that when I view an outline of the document, I can also see the custom environments.

For example, in the screenshot provided, neovim is showing the document symbols on the right side pane. I would like to have some mechanism so that I could specify to texlab which custom environments should also be included.

Thanks!
