Please help me on how to use trained model on Ameba Mini MCU

Hi,
I have train my Object Classification but I don’t know which option should I choose for my project. I am using Ameba Mini MCU for the project.

In This video https://www.youtube.com/watch?v=7YxshRJLCSk I can use CNN model to be use in the Ameba Mini. And the format supported is .h5 and it will be converted to .nb using AmebaIOT website (Amebapro2 AI Convert Model – Realtek IoT/Wi-Fi MCU Solutions).

So, may I know how to get .h5 file from Roboflow site to be use in my project?
