How can I render a div that has its visibility:'hidden'? in PDFjs

So I'm implementing a feature in my react web app, and in one of the Views, I have a button that takes 2 HTMLElements and display them in 2 pages in a PDF, but I would like one of them to stay hidden. The problem is that while hidden, PDFjs does not render it. Same happens when trying to set it to position:'absolute' and smth like '-999999px'.

This is the piece of code responsible for capturing and saving:

const downloadIt = () => {
    const blackboard = document.getElementById('blackboard') as HTMLElement;
    const descriptionList = document.getElementById('elementDescriptions') as HTMLElement;
  
    const width = blackboard.offsetWidth;
    const height = blackboard.offsetHeight;
    const aspectRatio = width / height;
  
    html2canvas(blackboard).then((canvas) => {
      const pdf = new jsPDF();
      const imageData = canvas.toDataURL('image/png');
      const pdfHeight = pdf.internal.pageSize.getWidth() * (1 / aspectRatio);
  
      pdf.text(comp.title, 8, 8);
      pdf.addImage(imageData, 'PNG', 15, 15, pdf.internal.pageSize.getWidth() - 20, pdfHeight);
  
      pdf.addPage();
  
      // Add the descriptionList to the PDF
      if (descriptionList) {
        html2canvas(descriptionList).then((descCanvas) => {
          const descData = descCanvas.toDataURL('image/png');
          const descAspectRatio = descCanvas.width / descCanvas.height;
          const descWidth = pdf.internal.pageSize.getWidth() - 190; // Adjust the margins as needed
          const descHeight = descWidth * (1 / descAspectRatio);
  
          pdf.addImage(descData, 'PNG', 15, 15, descWidth, descHeight);
  
          pdf.save(`${comp.title}.pdf`);
        });
      } else {
        pdf.save(`${comp.title}.pdf`);
      }
    });
  };

The one I'd like to hide is the one called descriptionList, just a simple div with some Cards inside.

I've tried moving it out of the way, but it keeps giving me an error of corrupt PNG file passed to PDFjs

Confusion between commands.Bot and discord.Client | Which one should I use?

Whenever you look at YouTube tutorials or code from this website there is a real variation. Some developers use client = discord.Client(intents=intents) while the others use bot = commands.Bot(command_prefix="something", intents=intents) . Now I know slightly about the difference but I get errors from different places from my code when I use either of them and its confusing. Especially since there has a few changes over the years in discord.py it is hard to find the real difference. I tried sticking to discord.Client then I found that there are more features in commands.Bot . Then I found errors when using commands.Bot . An example of this is: When I try to use commands.Bot client = commands.Bot(command_prefix=">",intents=intents) async def load(): for filename in os.listdir("./Cogs"): if filename.endswith(".py"): client.load_extension(f"Cogs.{filename[:-3]}") The above doesnt giveany response from my Cogs ...
