I have my doubts. Usually TextScript is not allowed in
ChordNames-context, unless you include the relevant engraver.

You need to iterate your function over the argument applying it to
every event-chord found.
Something at the lines of
diag=
#(define-music-function (parser location music)
(ly:music?)
(music-map
(lambda (m)
(if (music-is-of-type? m 'event-chord)
#{ <>^\markup \complete #m $m #}
m))
music))
And later:
\new ChordNames \with { \consists "Text_engraver" } \diag \chordNames
