Amazon web services – AWS S3 – how to prevent docs from downloading instead of displaying with pre-signed urls

This may seem like a question similar to others, but the focus is that it is a .doc file.

I am working with Python to generate AWS s3 pre-signed urls that looks like this:

def generate_s3_presigned_url(self, filename, expiration=300):
    try:
        mime_type = mimetypes.guess_type(filename)[0]
        # Generate the presigned URL
        presigned_url = self.client.generate_presigned_url(
                ClientMethod="get_object",
                Params={
                    "Bucket": self.bucket_name,
                    "Key": filename,
                    'ResponseContentType': mime_type,
                    'ResponseContentDisposition': 'inline',
                },
            ExpiresIn=expiration,  # Expiration time in seconds (300 seconds = 5 minutes)
            )

        return presigned_url

In this occasion I am working with Microsoft Word files, so the part 'ResponseContentType': mime_type is actually 'ResponseContentType': 'application/msword’.

Apparently, by adding the 'ResponseContentDisposition': ‘inline’ it was supposed to work but it didn’t.

When I am using the generated url the doc file keeps being downloaded no matter what I tried, but what I am trying to achieve is to display the doc file on my browser.
What can I do?
