PDF 图层不显示

我试图将水印显示为背景层，以便读者可以选择是否查看背景。我使用的是LuaLaTeX和xwatermark包。当我编译脚本时，背景和图层都不会出现。这是我的脚本的 MWE：

\documentclass[12pt,a4paper]{report}

\usepackage[no-math]{fontspec}
    \setmainfont{ArnoPro-Regular}

\usepackage{polyglossia}
    \setdefaultlanguage{english}
    \disablehyphenation

\usepackage[
    hmarginratio = 1:1,
    left = 3cm,
    right = 2cm,
    top = 3cm,
    bottom = 2cm,
    headheight = 15pt
    ]{geometry}

\usepackage{amsmath, amsthm, amssymb, amsfonts}

\usepackage[table]{xcolor}
    \definecolor{rowgrey}{rgb}{.9,.9,.9}
    \definecolor{heavengreen}{rgb}{.8901,.9568,.8941}
    \definecolor{greeen}{HTML}{7cc576}
    \definecolor{gold}{HTML}{f9ad81}
    \definecolor{smoofie}{HTML}{fff7ea}

\usepackage{pgfcore}
\usepackage[printwatermark,watermarkparser=|]{xwatermark}

\usepackage{tikz}
    \usetikzlibrary{backgrounds}

\usepackage{afterpage}
\usepackage{graphicx}
\usepackage{lipsum}
\usepackage[tikz]{ocgx2}

\begin{document}

\begin{titlepage}
    \pagecolor{smoofie}\afterpage{\nopagecolor}
    \begin{center}
        \vspace*{4cm}
        \begin{tikzpicture}
            \draw[line width=2mm,draw=greeen] (0,0) circle (4cm);
            \draw[line width=2mm,draw=gold] (0,0) circle (2cm);
        \end{tikzpicture}
    \end{center}
\end{titlepage}

\begin{ocg}{Background}{background}{true}
    \newwatermark[pages=1-5,angle=0,scale=2,xpos=0cm,ypos=0cm]{%
        \begin{tikzpicture}[opacity=.2]
            \fill [heavengreen] (-12,-5) rectangle (7,15);
            \draw[line width=2mm,draw=greeen,fill=heavengreen] (0,0) circle (4cm);
            \draw[line width=2mm,draw=gold] (0,0) circle (2cm);
        \end{tikzpicture}%
    }
\end{ocg}

\sloppy

\lipsum[1-12]

\end{document}

图层应该在水印内部定义，而不是相反：

\newwatermark[pages=1-5,angle=0,scale=2,xpos=0cm,ypos=0cm]{%
    \begin{ocg}{Background}{background}{true}%
        \begin{tikzpicture}[opacity=.2]
            \fill [heavengreen] (-12,-5) rectangle (7,15);
            \draw[line width=2mm,draw=greeen,fill=heavengreen] (0,0) circle (4cm);
            \draw[line width=2mm,draw=gold] (0,0) circle (2cm);
        \end{tikzpicture}%
    \end{ocg}%
}
