I'm creating an lwc component that shows a pdf with canvas, the lib I'm using is this:PDF,js when trying to load lib, returns me an undefined error, can someone help me how to load correctly

My Html

<template>
<lightning-card>
    <div class="container">
        <canvas id="the-canvas" class="canvas" lwc:dom="manual"></canvas>
    </div>
</lightning-card>    
</template>

My Js

import { LightningElement } from 'lwc';
import { ShowToastEvent } from 'lightning/platformShowToastEvent';
import { loadScript } from 'lightning/platformResourceLoader';
import PdfViewerJs from '@salesforce/resourceUrl/pdfViewer';

export default class compC21Body extends LightningElement {

 renderedCallback() {
    const jsPath = PdfViewerJs + '/pdf.js';
    window.console.log(jsPath);
    
    loadScript(this, jsPath).then(() => {
        window.console.log('success');
    }).catch(error => {
        window.console.log(error);
        this.dispatchEvent(
            new ShowToastEvent({
                title: 'Error Pdf Viewer',
                message: error ? error.message : 'We get error to load some script :/',
                variant: 'error',
            }),
        );
    });
  }
}

I put the lib build folder inside the statistic feature in salesforce Inside the static resource folder we have the files

• pdf.js
• pdf.js.map
• pdf.worker.js
• pdf.worker.js.map

if you have any library suggestions, I just need it to use canvas and not iframe
