I have a document management system where the documents are stored on AWS S3 and document metadata is stored in a NoSQL database. I want to integrate this with the SharePoint search. So that when a user search on Sharepoint that particular user should be able to see the search results from SharePoint documents + documents from the 3rd party system. What are the steps that I need to follow in order to integrate the documents in my application to Sharepoint search?

If the existing connectors don't fulfil your requirements, you can create your own custom connector:
