How to use custom-style for inline code and math?

[Lenv12138]

I want to use custom styles to render inline code(my inline test here) and multi-line equation($$\theta + 1$$) in Markdown. I defined two styles, namely "Equation" and "Inline Code", in the file "reference.docx". I want to make Panflute inform Pandoc to use the two styles I specify to render the content within inline code and multi-line equationin Markdown. How should I write the filter function?

I found that Pandoc uses the "First Paragraph" style from the "reference.docx" file for display math in panflute.

Besides, I have another question. When using pandoc to convert markdown to docx, why can't panflute recognize the identifiers of the following table?
