How to get AWS OpsWorks instance id within an instance?

Following is the way to get OpsWorks instance id of my current instance:

ec2_instance_id=$(ec2-metadata -i)

aws opsworks describe-stacks ---> returns all the stacks

iterate over all stack_ids from above:
    aws opsworks describe-instances --stack-id <stack-id>
    
    iterate over all instances from above:
         if ec2_instance_id == instance's ec2 id:
              return instance's opsworks id

But instead of this, is there any way to figure our the OpsWorks id from an instance? Is this information stored anywhere in the instance itself?

Every time I log in to an instance, it's summary is printed as follows:

 This instance is managed with AWS OpsWorks.

   ######  OpsWorks Summary  ######
   Operating System: Amazon Linux AMI release 2018.03
   OpsWorks Instance: XXXXXX
   OpsWorks Instance ID: XXXXXX
   OpsWorks Layers: XXXXXX
   OpsWorks Stack: XXXXXX
   EC2 Region: XXXXXX
   EC2 Availability Zone: XXXXX
   EC2 Instance ID: XXXXXX
   Public IP: XXXXXXX
   Private IP: XXXXXX
   VPC ID: XXXXX
   Subnet ID: XXXXX

Is there any file inside the instance where I can find this information?

On Amazon Linux 2, the ID is in /etc/aws/opsworks/instance-agent.yml

Thus you could get it:

ops_instance_id=$(sudo grep identity /etc/aws/opsworks/instance-agent.yml | cut -d ' ' -f2)

echo $ops_instance_id

example output:

54e0799e-bf86-426f-b08c-06530ca6b914

Maybe there is simpler way. I know only of the above one.
