Lichess Accessibility Mode?

A family member of mine would like to play chess, but cannot see well or move a mouse very easily. I searched online and see articles mentioning Lichess being accessible and even mentions of an "Enable blind mode" button (see this 2014 article: lichess.org/blog/U5AX_DcAADkAz-L5/accessibility-for-blind-players), but I can't find any button like this. Is there any more information on how to make Lichess accessible or am I missing something? Note, I do see an option for "Blindfold chess (invisible pieces)", but that's not what I'm looking for. Thanks!

Hello, I believe "blind mode" button is only easily accessible using a screenreader. In the blog, it says the button is one of the first elements on the page, so it should be immediately spoken by the screenreader and selectable.

Ironically, sighted users cannot see the "blind mode" button without opening source code:
