Can OpenMQTTGateway be the broker?

I have a Shelly smart switch with Tasmota on it outside the range of my Wifi. I do have LoRaWAN there, so I’m looking for a device that can act as an access point and MQTT broker so that Tasmota can connect to it and then forward the data over LoRa.

Can OpenMQTTGateway do that?
