Why can't I see the ec2 instance?

Question

Using aws iam, I am setting permissions for a group. I have set permissions for a specific group as follows, but the list of ec2 instances is not showing. What permission do I need to give to see the list of instances?

{
"Version": "2012-10-17",
"Statement": [
    {
        "Sid": "VisualEditor0",
        "Effect": "Allow",
        "Action": [
            "ec2:DescribeInstances",
            "s3:ListAllMyBuckets"
        ],
        "Resource": "*"
    },
    {
        "Sid": "VisualEditor1",
        "Effect": "Allow",
        "Action": [
            "s3:ListBucket",
            "s3:GetBucketVersioning"
        ],
        "Resource": "arn:aws:s3:::butket"
    }
]

}
