Hello - how would you go about adding the preview for this script?

EDIT:
I think I got it. Would love to get some feedback since this feels a bit too hacky.

# insert in line 29
--preview='cat $(tail -1 <<< {} | awk '\''BEGIN { FS = "\t" } { gsub(/ +$/, ".md", $1); print $1 }'\'')' --preview-window="right:50%:wrap" \
