Owners of digital Minecraft: XBOX One Edition asked to purchase Minecraft (Bedrock codebase)

I own Minecraft: xbox one edition in digital format. Today, I installed the latest update which announced the new better together version, which is cross-platform. On the update popup, I selected "Download Minecraft (New)." This just took me to the page for the new version in the store, but it was not free, as the message said. The price was $19.99.

How do XBOX One players who already own Minecraft download the new cross-platform capable version?
