How to read markdown file content from aws s3 in gatsby

[Sara14-sudo]

I am doing a blog project. I am doing it to read dynamically from S3 bucket. i am using plugin is /plugins/@robinmetral/gatsby-source-s3/ in s3 bucket.

There is bucket named tia, there is a file named post-1.md, its a markdown file. In post-1.md there is title, featured img URL, date and content. While using Alls3object query, I am getting displayed bucket name, key, URL only.

What I need is a query to display title, content, featured imgURL from post 1.md. We are not getting any query.

i am using this query

query IndexQuery {
allS3Image {
edges {
node {
Key
Url
}
}
}
}

only display key and url ...... What I need is a query to display title, content, featured imgURL from post 1.md. We are not getting any query.
