An error occurred (UnauthorizedOperation) when calling the DescribeLaunchTemplates operation?

I was trying to deploy launch template in my AWS autoscaling group using ansible!
Here was my script

- name: base64 conversion
  command: base64 -w 0 roles/inspect/tasks/user_data_cs.sh 
  register: userdata

- debug:
    var: userdata.stdout

#To deploy the user data in lauch template
- name: User data deployment
  ec2_launch_template:
    name: "{{ LT_name }}" 
    image_id: "ami-##########" 
    key_name: "aws-dev"
    block_device_mappings:
     - device_name: "/dev/sdb"
       ebs:
         volume_size: 20
         encrypted: true
     - device_name: "/dev/xvda"
       ebs:
         volume_size: 10
         volume_type: gp2
         delete_on_termination: yes
         encrypted: true
    default_version: 1
    ebs_optimized: no
    iam_instance_profile: "aws-ec2-role"
    network_interfaces:
    - device_index : 0
      delete_on_termination: yes
      associate_public_ip_address: no
      groups: ["sg-##########"]
    instance_type: t3.small
    user_data: "{{ userdata.stdout }}"
  when: name_env == "dev"

It was showing error

Here was my IAM permssions!
There seems to be no action as "DescribeLaunchTemplate"
I tried with autoscaling:DescribeLaunchTemplate elasticloadbalancing:DescribeLaunchTemplate
application-autoscaling:DescribeLaunchTemplate
also only
DescribeLaunchTemplate

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": [
                "elasticloadbalancing:DescribeLoadBalancers",
                "autoscaling:UpdateAutoScalingGroup",
                "autoscaling:CreateOrUpdateTags"
            ],
            "Resource": "*"
        }
    ]
}

and

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "VisualEditor0",
            "Effect": "Allow",
            "Action": [
                "application-autoscaling:RegisterScalableTarget",
                "application-autoscaling:DeleteScheduledAction",
                "application-autoscaling:DescribeScalableTargets",
                "application-autoscaling:DeleteScalingPolicy",
                "elasticloadbalancing:DescribeLoadBalancers",
                "autoscaling:DescribeAutoScalingGroups",
                "application-autoscaling:DescribeScalingActivities",
                "application-autoscaling:DescribeScalingPolicies",
                "application-autoscaling:PutScalingPolicy",
                "elasticloadbalancing:DescribeTargetGroups",
                "autoscaling:DescribeLoadBalancerTargetGroups",
                "application-autoscaling:DescribeScheduledActions",
                "application-autoscaling:PutScheduledAction",
                "application-autoscaling:DeregisterScalableTarget"
            ],
            "Resource": "*"
        }
    ]
}

I also tried adding "DescribeLaunchTemplates" but there seems to be no action on IAM like that checked with asg and everything.

Adding

"ec2:DescribeLaunchTemplates",
"ec2:DescribeLaunchTemplateVersions"

Resolved this issue
