Need to assign SSL certificate verified in AWS to EC2 Instance in AWS.

I have an instance running on my AWS console which is an application (vue/javascript) which is accessible on the web via a domain which I own. The SSL which had been assigned to the domain by the original app developer has recently expired. I need to renew it. I have created an SSL certificate application in AWS which I have verified via the domain DNS and which has been issued. However I do not know how to assign that SSL certificate to the EC2 instance such that the https prefix works with the domain when I attempt to access it on the web. I need specific instruction on exactly how to do this within the AWS console.
