Having error when I am trying to execute the python file in Ec2 (Windows) instance using lambda trigger

I am attempting to execute a Python file in an EC2 (Windows) instance through a lambda trigger function when a file is uploaded to an S3 bucket.

import boto3
import subprocess

def lambda_handler(event, context):
    instance_id = 'id-of-instance'
    
    directory = 'C:/Users/Administrator/Desktop/Automation'
    python_file = 'first.py'
    
    command = f'cd {directory} && python {python_file}'
    ec2 = boto3.client('ec2')

    response = ec2.send_command(
        InstanceIds=[instance_id],
        DocumentName='AWS-RunShellScript',
        Parameters={'commands': [command]}
    )

    return {
        'statusCode': 200,
        'body': response
    }

But it throws a error that is

Response
{
  "errorMessage": "'EC2' object has no attribute 'send_command'",
  "errorType": "AttributeError",
  "stackTrace": [
    "  File \"/var/task/lambda_function.py\", line 19, in lambda_handler\n    response = ec2.send_command(\n",
    "  File \"/var/runtime/botocore/client.py\", line 877, in __getattr__\n    f\"'{self.__class__.__name__}' object has no attribute '{item}'\"\n"
  ]
}
