See below:

;;; output begin here
             position: 14582 of 24975 (58%), column: 6
            character: $ (displayed as $) (codepoint 36, #o44, #x24)
              charset: ascii (ASCII (ISO646 IRV))
code point in charset: 0x24
               script: latin
               syntax: $     which means: math
             category: .:Base, a:ASCII, l:Latin, r:Roman
             to input: type "C-x 8 RET 24" or "C-x 8 RET DOLLAR SIGN"
          buffer code: #x24
            file code: #x24 (encoded by coding system utf-8-unix)
              display: by this font (glyph code):
    ftcrhb:-PfEd-DejaVuSansMono Nerd Font
Mono-regular-normal-normal-*-20-*-*-*-m-0-iso10646-1 (#x07)

Character code properties: customize what to show
  name: DOLLAR SIGN
  general-category: Sc (Symbol, Currency)
  decomposition: (36) ('$')

There are text properties here:
  face                 font-latex-math-face
  fontified            t
  wrap-prefix          " "
;;; output end here

This method works, as shown in the attached screenshot.
