Is there a way to get the entire selection in --preview

[u9g]

Hi, I'm making a help visualizer for nushell, but some of the commands have spaces like ansi gradient ... so in the help menu, they show up as ansi gradient, but then when I go to preview {1} I only get ansi, which is bad for getting more specific information about the command. I'm curious if there's a way to disable this splitting or get the whole selection that's highlighted. Here's my command so far:

help commands | get name | str join "\n" | fzf --preview-window 'up,60%,border-bottom,+{2}+3/3,~3' --preview "nu -c 'print {1}'"
