amazon web services - Gitlab runner auto-scale in Spot instance with IAM ROLE

Question

I am following this gitlab article on autoscaling gitlab runner on AWS spot instances.

I have a terraform code I need to execute and since these spot instances don't have an IAM role attached to them (since they are automatically spinning up by the runner) it gives me this pretty obvious error:

 Error creating VPC: UnauthorizedOperation: You are not authorized to perform this operation. Encoded authorization failure message

And this is my gitlab-runner config.toml, In here, where I can define the IAM role to be attached when the spot instance is spinning up ?

  [runners.machine]
    IdleCount = 1
    IdleTime = 1800
    MaxBuilds = 3
    MachineDriver = "amazonec2"
    MachineName = "shared-gitlab-runner-%s"
    MachineOptions = [
      "amazonec2-access-key=<ommited>",
      "amazonec2-secret-key=<ommited>",
      "amazonec2-region=us-east-2",
      "amazonec2-vpc-id=vpc-b76528dc",
      "amazonec2-subnet-id=subnet-d274q29e",
      "amazonec2-zone=c",
      "amazonec2-use-private-address=true",
      "amazonec2-tags=gitlab-aws-autoscaler,gitlab,true,gitlab-runner-autoscale,true",
      "amazonec2-security-group=ssh",
      "amazonec2-instance-type=t2.medium",
      "amazonec2-request-spot-instance=true",
      "amazonec2-spot-price=0.07",
      "amazonec2-block-duration-minutes=60"
    ]
