Ignition Edge MQTT Communication - Bidirectional?

Looking at Inductive Automation website, I’m not clear if the Edge license includes bi-directional MQTT communications or only one direction (PLC to Broker). It states “Publish field-device data through MQTT”. Can you confirm what is included in the license for Edge on the Groov?

The Opto 22 GROOV-LIC-EDGE8 includes the MQTT Transmission module. The Transmission Module publishes MQTT Sparkplug messages to the broker on tag data changes.

This also allows them to be consumed by a subscriber like MQTT Engine. MQTT Transmission also listens for commands via MQTT Sparkplug messages which then allows tag values to be written to remotely.

The communications can be bi-directional if the subscriber has the ability to send the appropriate commands.
