High Fidelity Image Trace Transparent Background

Hi,

When using High Fidelity Image Trace on a png image with transparent background, a white background is automatically created. With "High Fidelity", I can't click on "Ignore White" either. Surely there'd be a better option than individually deleting every single white path?? Why does Illustrator create a white background in the first place? Can anyone help me? Thank youuu!!!
