Как вернуть ввод текста в twilio

Question

Я относительно новичок в Киви.Я пытаюсь прочитать номер телефона, который вводится в текстовый ввод с помощью кнопки «Экстренные контакты» моего приложения.С этим номером я хотел бы отправить сообщение, используя twilio.Сообщение можно отправить, нажав кнопку «Позвонить семье» внутри кнопки «Просмотр сердечного ритма».Однако я не слишком уверен, как вернуть ввод текста, и небольшое руководство действительно поможет.

#twilio account info
#ACCOUNT SID AND TOKEN HERE. SORRY I CANT REALLY PROVIDE THEM 

account_sid = '--------------' 
auth_token = '------------'
client = Client(account_sid, auth_token)
