export.toDocx

Serialize a copy of the current document with independent policies for trackedChanges (review-preserving, final, original), comments (preserve, resolve, remove), and contentControls (preserve, flatten). Defaults preserve all three. Resolve closes every open comment thread in the copy. The mode alias selects trackedChanges; conflicting values and unknown policies reject with INVALID_INPUT. Unsupported revision semantics, loss of preserved comment anchors, and collaborative Document API export reject with CAPABILITY_UNSUPPORTED before returning bytes. Use browser export for collaborative sessions. Returns exported bytes and a structured report of allowed warnings without changing the live document.
