AWS Textract Analyze Expense how to extract data to my frontend application

Hello, I am doing an application that requires the use of textract analyzeExpense, in which I upload an image of an invoice or receipt and need to get the data that Textract extracts for me like Vendor, address, total, tax, etc. But I fail to find how to get the JSON data to my application, all the tutorials returns a CSV table to the s3 bucket.
