how to enable (https) SSL certificate AWS EC2 hosted site

So far i did below configuration.

1. I hosted my site on EC2 AWS machine. Public ip and public DNS.
2. I can access my website by ip as well as public DNS.
3. I purchased domain name from GoDaddy. www.xxtrasc.com
4. On AWS I created Hosted Zone then map www.app.xxtrasc.com successfully.

Now i access my website directly www.app.xxtrasc.com

1. On AWS Certificate Manager order certificate with domain name *.xxtrasc.comDid everything to add CNAME and all. I can see status gree colored Issued on ACM.

Now how i can attached this certificate to my web site so that i can access https://www.app.xxtrasc.com
