NSPanel Tasmota UI Lovelace - MQTT Publish commands / arguments?

Hi Guys,
Have a NSPanel runnings Tasmota LovelaceUI working well… What I am looking for is the MQTT publish commands to navigate to change pages on the NSpanel. ?
I knwo my MQTT is setup correctly and working as I can command.
Payload: CustomSend BUZZER 2,2,2 and the NSpanel internal buzzer sounds.
Does any body have a list of Payload commands I can send to the NSpanel to either change to a given page?
( example would be - Rear Door opens and NSpanel changes to Alarmpage. )
Many Thanks
