IAM Role not showing in aws console in Modify IAM role page

Question

I created an IAM role using the aws console and attached AmazonS3FullAccess policy. When I spun up an ec2 instance and tried to attach the profile, the profile does not show up in the list of available profile.

I have the following permissions:

"iam:PassRole",
"iam:ListInstanceProfiles"

What permissions do I need to list the profiles? Not sure what is missing, any help/guidance would be much appreciated.

Thank You!

You need the following as the Trust Relationship:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "Service": "ec2.amazonaws.com"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}
