How to use "Intents" rather than hard coded string detection?

[BenGWeeks]

In the code at the moment, it looks for hardcoded strings like "Send Zap". How do we change so that it uses the "intention" to send a zap to initiate the sendZap command, but you could use text such as "zap someone", "send sats", "zap them", "zap send", "zap", etc.
