How to download a private file from spaces using boto3

I can upload or someone uploaded a csv file into my spaces using boto3.

import boto3

session = boto3.session.Session()
client = session.client('s3',
                        endpoint_url=ENDPOINT_URL,
                        aws_access_key_id=ACCESS_KEY,
                        aws_secret_access_key=SECRET_KEY)

file_to_copy = 'myfile.csv'
dest_file = 'myfile.csv'
client.upload_file(file_to_copy, SPACE_NAME, dest_file)

The permission is set to private.

Now I want to read that file using pandas dataframe without setting the file to public and without the quick share feature though. Is that even possible using boto3? Or perhaps not boto3 as long as it uses python.

Note:

1. Setting the file to public, I can access it.
2. Sharing the file for 1 hour, etc. (quick share feature). I can access it too.

Thanks a lot.
