Updating Neo4j DB realtime - through AWS Lambda

I am looking for a solution to update Neo4J DB running on AWS through a serverless - Lambda function in real time - ie Lambda triggered through updates to a S3 bucket or a api end point call from a client app.I dont see any examples of such a lambda updates neo4j auradb in real time. Is this a validate scenario to update neo4j auraDB and later have the app query auradb in realtime ?
