I want to show pdf content with toolbar as above, but it’s only show pdf, How can I configuration to show the toolbar?

that’s my step:

1. I install pdfjs-dist: npm i pdfjs-dist
2. my code:

    const pdfUrl = 'https://raw.githubusercontent.com/mozilla/pdf.js/ba2edeae/web/compressed.tracemonkey-pldi-09.pdf';

    let pdfDoc = null,
        pageNum = 1,
        scale = 0.4,
        canvas = document.getElementById('pdf-canvas'),
        ctx = canvas.getContext('2d'),
        pageRendering = false,
        pageNumPending = null;

function showPdf() {
        pdfjsLib.getDocument(pdfUrl).promise.then(function(pdfDoc_) {
            console.log(pdfDoc_);
            pdfDoc = pdfDoc_;
            document.getElementById('page_count').textContent = pdfDoc.numPages;

            // Initial/first page rendering
            renderPage(pageNum);
        });
    }

    function renderPage(num) {
        pageRendering = true;
        pdfDoc.getPage(num).then(function(page) {
            const viewport = page.getViewport({scale: scale});
            canvas.height = viewport.height;
            canvas.width = viewport.width;

            // Render PDF page into canvas context
            const renderContext = {
                canvasContext: ctx,
                viewport: viewport
            };
            const renderTask = page.render(renderContext);

            renderTask.promise.then(function() {
                pageRendering = false;
                if (pageNumPending !== null) {
                // New page rendering is pending
                renderPage(pageNumPending);
                pageNumPending = null;
                }
            });
        });
    }

html:

<button type="button" class="btn btn-outline-secondary" @click="showPdf();">PDF</button>

<div class="p-2 border">
    <canvas id="pdf-canvas"></canvas>
</div>

import:

import 'pdfjs-dist/build/pdf.min.mjs';
import * as pdfjsLib from 'pdfjs-dist/build/pdf.min.mjs';

pdfjsLib.GlobalWorkerOptions.workerSrc = `https://cdnjs.cloudflare.com/ajax/libs/pdf.js/${pdfjsLib.version}/pdf.worker.min.js`;
window.pdfjsLib = pdfjsLib;

I try to customize a simple toolbar but take too much time, Somebody help..!
