I stand corrected. Still, even without a duration passed
to \tuplet, the TupletBracket and TupletNumber appear
missing.

\version "2.23.4"

\new Staff \with {
  \override TupletBracket.bracket-visibility = ##t
}
<<
  { \voiceOne \tuplet 3/2 \grace { e'8 8 8 } 1 }

  { \voiceTwo \grace \tuplet 3/2 { c'8 8 8 } 1 }
