Can't download file in macOS Safari Excel add-in

Question

So, I'm developing an Excel add-in in macOS. I'm trying to create a file and download it then in browser. Here is the code (I'm using saveAs function from file-saver package):

async function saveFile(workbook: ExcelJS.Workbook, id) {
    const xls64 = await workbook.xlsx.writeBuffer();
    const blob = new Blob([xls64], { type: 'application/xlsx' });
    saveAs(blob, `${id}.xlsx`);
}

Also, I was trying to download file by this way:

function download(url, filename) {
fetch(url)
    .then((response) => response.blob())
    .then((blob) => {
        const link = document.createElement('a');
        link.href = URL.createObjectURL(blob);
        link.download = filename;
        link.click();
        console.log(link);
    })
    .catch(console.error);
 }

But it doesn't work as well. Type of file doesn't matter also.

In Edge (Windows add-in version) it works, while in Safari (macOS add-in) it doesn't... Also, I can download files when I open localhost in Safari browser outside the add-in. I see no errors in logs.

Could you help me out how to write code to download file in macOS add-in?
