It's easier to help if you provide a source code as starting point.

Here one possibility, adapted from the documentation:

\version "2.22.0"

% modify half-diminished chord
% Exception music is chords with markups
chExceptionMusic = {
  <c es ges bes>1-\markup { m\super { 7(\flat 5) } }
}

% Convert music to list and prepend to existing exceptions.
chExceptions =
#(append
  (sequential-music-to-chord-exceptions chExceptionMusic #t)
  ignatzekExceptions)

\layout {
  \set chordNameExceptions = #chExceptions
}

theMusic = \chordmode {
  g1:m7.5-
}

\layout {
  ragged-right = ##t
}

<<
  \context ChordNames \theMusic
  \context Voice \theMusic
>>
