I am trying to implement a way for resuming a chunk file upload based on the last successfully uploaded index (assuming that the .remove() functionality was not used to delete the previous attempt from the server). ChatGPT seems to think this is possible by setting chunkIndex property of e.data in the upload function, but that doesn't seem to affect the starting index based on the ChunkIndex passed in the MetaData property of the subsequent API call. Is there a way to set the starting index of a chunk upload?
