TOOL API

doc.insert_header

Sets the header text of a Tencent Docs document, overwriting any existing header content in the target section. It handles one section per call (given by section_index), so call it once per section you want to update; the first insert creates a separate header/footer substory for that section and breaks its "link to previous" relationship. If both tencent-docs (personal) and tencent-docs-oa (enterprise) are connected, use AskUserQuestion to let the user pick the target account before invoking this tool.
