adding properly text gradient to my svg component

I'm trying to add the gradient on text for my svg image.

Here's my svg image:

i've uploaded here in png format That's the way I'm trying to do that:

export const HawllIcon: React.FC<IconSvgProps> = ({
  size = 100,
  width,
  height,
  ...props
}: IconSvgProps) => (
  <svg
    height={size || height}
    preserveAspectRatio="xMidYMid meet"
    version="1.0"
    viewBox="0 0 800 500"
    width={size || width}
    {...props}
    xmlns="http://www.w3.org/2000/svg"
  >
    <defs>
      <linearGradient id="MyGradient" x1="0%" x2="100%" y1="0%" y2="100%">
        <stop offset="5%" stopColor="#ff9459" />
        <stop offset="95%" stopColor="#006fee" />
      </linearGradient>
    </defs>
    <g
      fill="url(#MyGradient)"
      stroke="none"
      transform="translate(0,500) scale(0.1,-0.1)"
    >

);

But I'm only achieving this:

And I'm trying to achieve that:

What do I need to do to get things done?

I've tried to:

• change fill to almost every variation of this gradient,
• change the gradientUnits both ways: objectBoundingBox & userSpaceOnUse and none of them does the thing correctly.

You can use the letters in a mask, and mask off a rectangle that has the gradient fill.

body {
  background: black;
}
