End-to-end Encrypted Messaging with Ockam - and (smartphone-) Apps

At ElixirConf there was this great talk about Intro to Ockam | Ockam

This seems like exactly what I need, but I wonder how can a smartphone app participate in encrypted ockam communication? There seems to be only Elixir and Rust SDKs. Most interested in how to use it with flutter.

Just watched this vid when searching for End-to-end encryption in Elixir. Is anyone using it in their apps?
It’s a bit light on Elixir documentation (only Elixir code examples provided). How does one set this up in Liveview?
