Delivering live streaming video with CloudFront and AWS Media Services

Question

i am creating react app by following https://github.com/aws-solutions/live-stream-on-aws github repo to implement live-stream-on-aws. I understood the steps of starting live, but i got stuck on cloud front. in this repo there is every step of how to create the input, medialive channel, mediapackage channel, endpoint. But i was not able to find connecting mediapackage to cloudfront. the steps i am doing in node js:

create media package, create endpoint, create input security group, create input, create media live channel,

in this process i am able to play live stream with endpoint url, but it is said that i have to broadcast the live on cloudfront. How can i connect cloudfront. Or is there any github repo like above one? If you can help, i would really appreciate it! Thank you very much!

IN the read me file of the repo it is clearly described the process as an image (https://github.com/aws-solutions/live-stream-on-aws#live-streaming-on-aws) if check at the end of the process there is cloudfront. in the source code i was not able to find even the word "cloudfront".
