Use the notification plugin purely from Rust

I've been scratching my head with the notification plugin and how I can use it purely from Rust with no frontend code. I can see most things are exposed but there are some things I can't reason about.
When trying to create actions, the Action Types and Action properties are all private and there's no constructor or builder for them so you can't instantiate it (at least from what I could find), and I am not sure how to listen to notifications being interacted with or the actions via Rust. Only the frontend APIs that are exposed.

Can I be advised on if this is possible currently, or if there are any work arounds? Thanks.
