'Change DP Code' function not working for me

[zero1niner]

I have a LegendFlame electric fireplace thats got a tuya app integration. The 'switch' function turns on the heater, not the flame light. In the IOT.tuya, i can get using the debug tool, I can get the the flame to turn on and off by using:
[ { "code": "light", "value": false } ]

So I tried to follow the instructions shown on the ADVANCED_OPTIONS.md for '[Change DP code](Change DP code)' and added the following:
"schema": [ { "code": "switch", "newCode": "light"

When I check the logs, the 'switch' code is still being sent, and not the 'light' command.

Im kinda new to this, so not sure how to troubleshoot this. Any suggestions?
