HiveMQ Edge - modbus

Hello
Does HiveMQ Edge support ModBus Write Commands?
If so - available in open source or commerical offering?
If not - can it be developed via plugins?

Any discussion on basically write commands on the soutbound connectors would be great.
TIA

Extra:
Unable to join the community slack - how to do so? on webpage say need a @hivemq email account.

Thanks
Ed
