Any reference design for nfc wireless charging?

I just read this document : https://www.st.com/content/dam/specialevents-assets/dc22/pdf/room-3-1-stdevcon22-session-nfc-for-wireless-charging.pdf

In page 13, there are two daughter boards, one based on ST25R3916 (NFC reader) and the other based on ST25DV-I2C (NFC dynamic tag). Both use STM32L476 as motherboard. In the following pages, they demonstrated an 286mw power transfer with the small antenna on boards. Which is a nice result.

My question: does ST sell the two daughter boards and provide code and hardware design files as an official reference design? Or there are other kit for evaluating this solution? We are looking for a reference design based on STM32R3916/ST25DV-I2C. Also we are planning to use this solution in our medical device project.

    Hi,
    Have you developed any device where you charge the device using the mentioned ICs. We have developed the same and have used very small antenna of the size 12mm x 7mm. We can charge the device. However there is problem reading the ST25DV IC as NFC tag. Just wanted to discuss that.
