+/**
+ * Update the provided TOC to allow collapsing its entries with Bootstrap's accordion.
+ *
+ * The typical structure of a TOC menu is a follows:
+ * <ul><li>
+ *     <a href="#"/>
+ *     <ul>
+ *         <li><a href="#heading_without_child"/></li>
+ *         <li>
+ *             <a href="#heading_with_children"/>
+ *             <ul>...</ul>
+ *         </li>
+ *     </ul>
+ * </li></ul>
+ *
+ * Since a <ul> is always preceded by a <a>, and since we only need to make change to <a>
+ * elements followed by a <ul>, we simply loop on <ul> elements to access all parts of the DOM
+ * that need to be modified.
+ *
+ * The final structure must look like this:
+ * <ul><li>
+ *     <!-- Only <a> element with empty href must expand/collapse on click -->
+ *     <a href="#" data-bs-target="#o_target_{id}>" data-bs-toggle="collapse"/>
+ *     <ul>
+ *         <li><a href="#heading_without_child"/></li>
+ *         <li>
+ *             <div class="o_toc_entry_wrapper">
+ *                 <i class="i-chevron-right" data-bs-target="#o_target_{id}" data-bs-toggle="collapse"/>
+ *                 <a href="#heading_with_children"/>
+ *             </div>
+ *             <ul id="o_target_{id}" class="collapse">...</ul>
+ *         </li>
+ *     </ul>
+ * </li></ul>
+ *
+ * @param {HTMLElement} tocElement - The element containing the TOC
