Where do I add style word-break keep-all in Microsoft Lists for JSON

Sorry I am having trouble figuring out where to add some JSON for word wrap.

I don't know where to add style word-break keep all

I have a Microsoft Lists that I'd like to have the words wrap in Gallery mode.

For the top line, no need, no problem, the next line, some could use some word wrap.

If I make ALL of them 1024 it will be a "list" instead of this gallery.

I found online that people use style work break keep all.  I am not sure where to put it.  I tried to just ADD it in the code and it is obviously NOT working when I do preview.

This is the start of the JSON
