Accepting Join Request

Good day,

How can a join request be accepted on MQTT?

The setup is the network bridge is installed on my gateway and I am receiving join requests from a device. How can I respond to it on MQTT I do not want to interact with MQTT from the application server. I want to respond to it on MQTT directly.

Is this a possibility?

Regards

Join requests are handled by the ChirpStack network server. Is your device registered and configured correctly, such that the network server can respond?
