// associate event handler for the onSubmitSuccess event
<AdaptiveForm mappings={extendMappings} onSubmitSuccess={onSuccess} formJson={selectedForm}/>

// extract the json returned by the custom submit service
const onSuccess=(action) =>{
        let body = action.payload?.body;
        let FirstName = JSON.parse(body.metadata.json).firstName;
        setThankYouMessage(FirstName+" your request has been received");

      }
