How to make the vehicle pop up a reminder of low key power?

[zhy2020]

I've been using your library PyTeslaBLE recently. I want to send a message to tell the car that the key device battery is low and have the car pop-up window prompt. What message should I generate? I found a 'KeyfobInfo message', but I don't know how to use it. Can you help me look at it? thanks.
