How to make a call and send digits in Twilio

I'm attempting to make a call to an IVR. While calling the number, I want to input digits. I followed this video for making the call, but how can I send digits?

@evan @victoria could you please assist me with this

Hey @kum Can you share a bit more about your ask? Where / how are you attempting to send the digits? Can you share what you've built so far and what errors you are hitting?
