Duplicate an order on the Shopify app?

The Shopify help page on Draft Orders mentions the following:

Open the order (or the draft order) from the Orders page in your Shopify admin.

In the order (or draft order) details page, click Duplicate.

I cannot find any "Duplicate" button or link on the order page within the Shopify app.
Monster, creature & cryptozoology patches, buttons & stickers.
