mDash console logging

Hi,

I see that mos supports console through mdash: https://github.com/cesanta/mos-tool/commit/1df218feebf424982a225c8d890187ce3102f7a4

However when I try to connect I get an error:
“Error: /src/go/src/github.com/mongoose-os/mos/cli/dev/dev_conn_impl.go:171: remote error 404: No handler for Dash.Console.Subscribe”
It’s self descriptive - I do not have such rpc on my device and have not found it anywhere - https://github.com/mongoose-os-libs/
Is this functionality available to the public and where should I search for the needed lib?

Thanks.
