Sending "ping" and "pong" messages to Solokey extension

[nakatsuka-y]

Hello,

This tutorial shows us how to implement a Solokey extension where we can exchange "ping" and "pong" messages.

So far, I was able to implement, build, and upload the updated firmware to my Solokey.

However, the document doesn't mention how to send messages to Solokey.
I didn't find any issues and documents in this repo that provides instructions on how to do this.

Can anyone help me with this?
I'd be happy to update the documentation if I've managed to send the messages :)

Thanks!
