Initialize the Upload
When a user selects a file, the LWC first retrieves the S3 upload parameters using the
Salesforce Connect API.
This retrieval is done through an Apex class (ConnectApiHelper) that calls the initializeFileUpload method. See initializeFileUpload(inputRep) to learn about the signature and parameters of the method.
