如何使用 aws s3api 将 acl 策略应用于 S3 存储桶中的子文件夹

Question

I have few folders in S3 bucket where I want to apply the below policy and also to the subfolders inside the specified path.

aws s3api put-object-acl --bucket BUCKET_NAME --key "FOLDER_PATH/" --grant-read uri=http://acs.amazonaws.com/groups/global/AllUsers --profile MYPROFILE

I cannot use regex * in the key so that it includes all subfolders.

Help me apply the policy to all subfolders inside the key path.

import boto3
import os

def lambda_handler(event, context):
        prefix = "folderpath" #folder path without trailing slash (eg foldername1/foldername2 )
        bucket = 'bucketnamehere' # S3 bucket name here
        s3 = boto3.resource('s3')
        bucket = s3.Bucket(name=bucket)
        s3_cl = boto3.client('s3')
        for obj in bucket.objects.filter(Prefix=prefix):
                folders = obj.key
                if(folders[-1] == '/'):
                        print(folders)
                        # Add ACL policy here
