How to keep admonitions in markdown -- pandoc --> docx convertion?

[sylvaticus]

I have a Markdown source, cuirrently using admonitions in !!! TIP format (but I can eventually change this). How do I keep admonitions, possibly with an icon, when converrting to docx format using pandoc ?

EDIT:

I think I managed getting an icon, but how do I wrap the whole div in a docx style that I can then personalize in the docx itself ?:

Markdon source:

aaa

::: {.tip}
Some Text bbb
:::

ccc

Lua filter:

(admonition.lua)

local admonitions = {
  warning   = {pandoc.Str("Warning")},
  note      = {pandoc.Str("Note!")},
  tip       = {pandoc.Image("Tipping hat", "hat-tip.jpg"),
               pandoc.Str("Tip"),
               pandoc.Space()},
  important = {pandoc.Str("Important!")},
  caution   = {pandoc.Str("Caution!")}
  }

function Div(el)
  local admonition_text = admonitions[el.classes[1]]
  if admonition_text then
    table.insert(el.content, 1,
        pandoc.Para{ pandoc.Strong(admonition_text) })
  end
  return el
end

Command line conversion:

pandoc source.md --lua-filter admonition.lua --from markdown+fenced_divs -o output.docx

Result:

As you can see, I have the icon but the content of the tip is in the same style as the rest of the document. How can I have a style that inglobe the tip (warning, note....) header and the tip content ?

I have found the option reference-doc, so I have used a pandoc-generated docx, created and edited a style "Annotation_tip" and I use it with the reference-doc.
How do I now specify that the whole anotation box should use the Annotation_tip style ?

I have found something like pandoc.Attr("", {}, {["custom-style"]="Annotation_tip"})) but I don't know how to apply it in the context of the lua filter above.

At the end I think I got it:

Lua filter (admonition.lua):

function convert(blk)
  if blk.t == "Div" then
    if type(blk.classes) == "table" then  -- Ensure blk.classes is a table
      if blk.classes[1] ~= nil then  -- Check if there is an entry at index 1
        if blk.classes[1] == "warning" then
          return pandoc.Div({blk}, pandoc.Attr("", {}, {["custom-style"]="Annotation_warning"}))
        elseif blk.classes[1] == "note" then
          return pandoc.Div({blk}, pandoc.Attr("", {}, {["custom-style"]="Annotation_note"}))
        elseif blk.classes[1] == "tip" then
          return pandoc.Div({blk}, pandoc.Attr("", {}, {["custom-style"]="Annotation_tip"}))
        elseif blk.classes[1] == "important" then
          return pandoc.Div({blk}, pandoc.Attr("", {}, {["custom-style"]="Annotation_important"}))
        elseif blk.classes[1] == "caution" then
          return pandoc.Div({blk}, pandoc.Attr("", {}, {["custom-style"]="Annotation_caution"}))
        end  
      end
    end
  end
  return blk
end


function Pandoc(doc)
   local out = doc.blocks:map(convert)
   return pandoc.Pandoc(out, doc.meta)
end

local admonitions = {
  warning   = {pandoc.Image("Warning", "imgs/admonitions/adm_warning.png"),pandoc.Space(), pandoc.Str("Warning !")},
  note      = {pandoc.Image("Note", "imgs/admonitions/adm_note.png"),pandoc.Space(), pandoc.Str("Note")},
  tip       = {pandoc.Image("Tip", "imgs/admonitions/adm_tip.png"),pandoc.Space(), pandoc.Str("Tip")},
  important = {pandoc.Image("Important", "imgs/admonitions/adm_important.png"),pandoc.Space(), pandoc.Str("Important !")},
  caution   = {pandoc.Image("Caution", "imgs/admonitions/adm_caution.png"),pandoc.Space(), pandoc.Str("Caution")},
  }

function Div(el)
  local admonition_text = admonitions[el.classes[1]]
  if admonition_text then
    table.insert(el.content, 1,
        pandoc.Para{ pandoc.Strong(admonition_text)})
  end
  return el
end

Comand line:

pandoc source.md --lua-filter admonition.lua --from markdown+fenced_divs --reference-doc=a_docx_file_with_the_required_styles.docx -o output.docx
