Passage to 2.23 still a problem with scheme

[Vincent Gay]

    Good evening to all
    
    I frequently use opening and closing parenthesis to frame not only
    one note or chord but several. For example :

    or

    The lsr snippet : https://lsr.di.unimi.it/LSR/Item?id=902
    
    here is a minimal example in 2.22.2
    
    %%%%%%%%%%%%%%%
    startParenthesis = {
      \once \override ParenthesesItem.stencils = #(lambda (grob)
                                                    (let ((par-list
    (parentheses-item::calc-parenthesis-stencils grob)))
                                                      (list (car
    par-list) point-stencil )))
    }
    endParenthesis = {
      \once \override ParenthesesItem.stencils = #(lambda (grob)
                                                    (let ((par-list
    (parentheses-item::calc-parenthesis-stencils grob)))
                                                      (list
    point-stencil (cadr par-list))))
    }
    
    {  c1 \startParenthesis \parenthesize  c c \endParenthesis
    \parenthesize   }
    %%%%%%%%%%%%%%%
    
    but I know that the handling of parentheses had changed a lot with
    2.23, and that parentheses-item does not exist anymore. In fact it
    doesn't work anymore even after a convert-ly.
    
    Lily's message:

/tmp/Parentheses.ly:7:19: error: bad grob property path

\once \override

ParenthesesItem.stencils = #(lambda (grob)

/tmp/Parentheses.ly:12:19: error: bad grob property path

\once \override

ParenthesesItem.stencils = #(lambda (grob)

/tmp/Parentheses.ly:17:76: error: syntax error, unexpected '}', expecting \header

{ c1 \startParenthesis \parenthesize c c \endParenthesis \parenthesize

}

/tmp/Parentheses.ly:17:1: error: errors found, ignoring music _expression_

    Does anyone know of another solution, or would they know how to
    change this?
    
    Thanks in advance
