[Python] Is there a way to cancel/abort Flet.FilePicker.update() when use it with Minio/s3...

i'm a newbie to Flet and i can't solve this problem. After the command:

file_picker.upload([FilePickerUploadFile(name=filename,upload_url=presigned_url)])


Object from userside' files start to be uploaded to object storage, but is there a way for user to abort the uploading?

I make some experiments and find that whenever user refresh or close the page, the upload process is interrupted. But i can't find the way so that user clink a button, the process stop immediately in hand.

Thank you.
