Adds an intent handler for incoming intents. The last intent sent of the name subscribed to will be received.
Example
const intentHandler = (intent) => {
const { context } = intent;
myViewChartHandler(context);
};
const subscription = await fin.me.interop.registerIntentHandler(intentHandler, 'ViewChart');
function myAppCloseSequence() {
// to unsubscribe the handler, simply call:
subscription.unsubscribe();
}
