I have already implemented pdfjs in react, and it is working normally. But my issue is that i can't pinch to zoom in, and i couldn't find any resources that can help with my current code.

Please find my code below

JS

  const renderPage = useCallback(
    (pageNum, pdf = pdfRef) => {
      pdf &&
        pdf.getPage(pageNum).then(async (page) => {
          const canvas = canvasRef.current;
          const viewport = page.getViewport({ scale: 1 });
          canvas.height = viewport.height;
          canvas.width = viewport.width;
          const renderContext = {
            canvasContext: canvas.getContext('2d'),
            viewport,
          };
          updatePageLoadingStatus(true);
          await page.render(renderContext);
          updatePageLoadingStatus(false);
        });
    },
    [pdfRef],
  );

HTML

<canvas ref={canvasRef} />

I appreciate any help with solving the pinch to zoom issue.
