Function record_invocation 

pub fn record_invocation(
    invocation: InvocationId,
    app: &str,
    action: &str,
    arguments: Map<String, Value>,
) -> InvokeRequest

The invocation that asks a host to run action of app’s workspace record with arguments: the record’s own resource, as the app’s door offers it. The receipt is held until the action settles, so a reading answers at once and one that went elsewhere answers once it is back.
