Set header collapse indicators to always on?

How can I set header fold/collapse indicators to always show the little icon to fold text? Also, for when text is under a line then tab/indented thus folded.

I think that second fold way (without it being a header) is a setting I switched on?

This is with the minimal theme, I’ve looked through Obsidian settings, minimal settings, style settings, and can’t find where to change that or if it’s possible. Maybe needs a css snippet?
