How to have a function called when the uploader is finished creating a base64 image

[jsd3]

I'd like to be able to register a callback function to be called after an image is converted to base64 encoding when the
uploader option insertImageAsBase64URI is set to true:

const editor = Jodit.make('#' + targetTextAreaId , { uploader: { insertImageAsBase64URI: true, imagesExtensions: [ "jpg", "png", ...

I also want the original image filename - how can I get this? Thanks so much for any help!
