Trigger "Custom" msg Alexa Announce using Service Call via Node Red

Hi Guys,

I’m a complete newbie to NodeRed and slowly learning my way on how to get automations done in NodeRed.

At present i can do a Alexa announcement using a Service Call, Notify_Alexa. I intend to use this service call more often for a variety of automations i plan to incorporate.

Is there a best practice on how i can get this done, when i just send customize payload data using a Function to just 1 Alexa Service call node to do the TTS/Announce.

Im not sure how to get this done the right way.

Cheers!!
