Remove trailing slashes from AWS S3 stating webhosting site

I have generated my WordPress website as static html and deployed it to s3 bucket to serve as static website.

Here is my website endpoint: wwwalls.com

My SEO team wants that the page URLs must not contain trailing slashes, but I could not find any document online that could allow me to get rid of trailing slashes from the URL eg : https://wwwalls.com/demo leads to https://wwwalls.com/demo/

I tried using redirects but then it ends up in too many redirects.

[
    {
        "Condition": {
            "KeyPrefixEquals": "demo/"
        },
        "Redirect": {
            "ReplaceKeyPrefixWith": "demo"
        }
    }
]

Please advice !
