Channels: (?)

I would like to know if the channels of the main chat platforms (Slack, Facebook, Telegram, etc.) that were traditionally supported by Botpress, will continue to be officially supported in the new version (11.0 and higher).

These channels have been removed from this repository. I suppose that they will become external modules, but at the moment there are no instructions to install them, and they doesn't seem to be available.

Any bot built using Botpress 10.x and published on these channels will not be able to migrate to 11.x.

Could you shed some light on this matter?

Thanks in advance.
