If you are injecting an ancor tag into DOM programmatically as your solution, make sure you do not clear that up too soon.

For me 100ms worked fine but since it's invisible either way I chose 1 second delay on clearing DOM up.

Example code:

this.fileApi.download(<your args>).subscribe((data: Blob) => {
    const url = window.URL.createObjectURL(data);
    const a = document.createElement('a');
    a.style.display = 'none';
    a.href = url;

    // the filename you want
    a.download = <your filename>;
    document.body.appendChild(a);
    a.click();

    setTimeout(() => {
      window.URL.revokeObjectURL(url);
      document.body.removeChild(a);
    }, 1000);
  })
