How to add crop feature with react js?

Hi,
I’ve just started using this amazing library of yours and simple love it.
I followed the instructions and used the

import { Widget } from ‘@uploadcare/react-widget’
and

<Widget
tabs=‘file’
previewStep={true}
imagesOnly={true}
multiple={false}
crop=‘4:3’
publicKey={process.env.NEXT_PUBLIC_UPLOADER_PUB_KEY}
onFileSelect={(e) => {
e.done((file) => {
console.log(file.originalUrl);
formikBag.values.pictureUrl = file.originalUrl;
setFieldValue(‘pictureUrl’, file.originalUrl);
});
}}
/>

my images are uploading successfully, however they’re not being cropped, what am I doing wrong?
