Rendering images in version 4

[markb-trustifi]

NodeJS: 20.13.1
I want to render single image from the PDF. In version 3 I did it this way:

const {convertToRGBA} = require('pdfjs-dist/lib/shared/image_utils');
imageInfo = page.objs.get(operators.argsArray[j][0]);
let canvas = Canvas.createCanvas(imageInfo.width, imageInfo.height);
let ctx = canvas.getContext('2d');
let imageData = ctx.createImageData(imageInfo.width, imageInfo.height);
if (!convertToRGBA({kind: imageInfo.kind, width: imageInfo.width, height: imageInfo.height, src: imageInfo.data, dest: new Uint32Array(imageData.data.buffer)})) {
   imageData.data.set(imageInfo.data);
}
ctx.putImageData(imageData, 0, 0);

The function convertToRGBA is very important here, because it fixes rendering of 1bit black-and-white and 24bit color images.
On the other hand, in the version 4 this function is not exported from pdfjsLib, as well as this function CanvasGraphics.paintImageXObject(objId) is not exported too.

pdfjsLib is built without "lib" folder.
What are you doing in this case?

I found solution, I take it from the source package:
const {convertToRGBA} = await import('pdf.js/src/shared/image_utils.js');
