How to use messages.getMessageReactionsList for Telegram bot using telegram-bot crate

Hi, this is my first rust project.
I'm trying to write telegram bot using telegram-bot crate. Inside it there is no library for API for getting reactions on messages. I tried searching all rust libraries recommended by telegram on tg page, but none of libraries seem to implement this method.

Now, I have no idea how to write lib for this telegram API since it's way above my rust knowledge. Could someone point me to library that implements this, or maybe even better show me how to write it for this API, using this telegram-bot crate?
