Issue in AWS IoT integration downlink messages and topic

Issue: I have done AWS IoT integration In RAK7268V2 and added a node, but facing issue in sending downlink message to the node.

Setup: RAK7268V2

Device:
I have done AWS IoT Core Integration with built-in server mode, I have deployed a node with application name as water_sensors_blr and devEUI as 8cc302320xxxxxxx, but I am receiving the proper uplink message in topic as

application/wate/device/8cc302320xxxxxxx/rx

so when I am trying to send a dowlink message from aws iot with same topic, node is not receiving the data,

application/wate/device/8cc302320xxxxxxx/tx

I have changed the topic as below , even then node is not receiving the data,

application/water_sensors_blr/device/8cc302320xxxxxxx/tx
