As a matter of style, I'd do it slightly differently:

\version "2.23.4"

\layout {
  \context {
    \Staff
    \accepts ChordNames
    \override ChordName.Y-offset = #self-alignment-interface::y-aligned-on-self
    \override ChordName.self-alignment-Y = #CENTER
  }
}

harmony =  \chordmode { a1:m s1 f1:m7 s1 }
tune = { s1 s1 s1 s1 }


\new Staff <<
  \tune
  \new ChordNames \harmony
>>
