I can‘t customize a circular team logo with a transparent background,Pls Help!!!

[DaleX0]

When using F1 Manager Save Browser, I want to create a fleet logo with a transparent background.However, when I uploaded an image with a completely transparent background and used the Logo editor to generate the icon, what I got was a logo with a white background
I really want to directly generate a team logo with a completely transparent background. Is this a solvable problem? If possible, please ask me how to solve it. Thank you very much.

you can still use that editor to remove the white background?
