1. First, let's create a "paper", assuming that the text has been written and endnotes have been inserted. As shown in the figure. The left column is the table of contents.

Next, suppose you want to add an appendix and insert a blank page at the back.

3. Next, we need to insert a breakpoint at the end of the text, position the cursor at the last blank position of the text, there is a break item under the page layout of the toolbar, and click the small inverted triangle in the lower right corner.

4. Select the next page under section break. As shown in the figure.

5. At this time, we click on the small arrow in the lower right corner of "Quotation" and a dialog box appears, as shown in the figure.

6. Click the Endnote drop-down box, select Ending, and then click Apply.

7. Then close the dialog box, and you can add "Appendix" after the endnote, as shown in the figure.
