[Custom Layout] How to extend Two Pane to have the main pane width an exact number

As the title says, I'm trying to extend the Two Pane layout, but making the main pane a width of 2560px.

This is the code I have that doesn't work:

function layout() {
  return {
    name: "presentation",
    extends: "two-pane",
    getFrameAssignments: (windows, screenFrame, extendedFrames) => {
      const mainWidth = 2560;

      return extendedFrames.reduce((frames, extendedFrame) => {
        let frame;
        if (index === 0) {
          frame = {
            x: extendedFrame.x,
            y: extendedFrame.y,
            width: mainWidth,
            height: extendedFrame.height,
          };
        } else {
          frame = {
            x: extendedFrame.x,
            y: extendedFrame.y,
            width: extendedFrame.width,
            height: extendedFrame.height,
          };
        }
        return { ...frames, [extendedFrame.id]: frame };
      }, {});
    },
  };
}

Sorry, I'm a billion years late on this, but it doesn't look like index is actually defined anywhere?

Thanks for the reply. I used extended.js and static-ratio-tall.js as inspirations but no luck.

function layout() {
  return {
    name: "Presentation",
    extends: "two-pane",
    getFrameAssignments: (windows, extendedFrames) => {
      const mainWidth = 2560;

      return extendedFrames.reduce((frames, extendedFrame, index) => {
        let frame;
        if (index === 0) {
          frame = {
            x: extendedFrame.frame.x,
            y: extendedFrame.frame.y,
            width: mainWidth,
            height: extendedFrame.frame.height,
          };
        } else {
          frame = {
            x: extendedFrame.frame.x,
            y: extendedFrame.frame.y,
            width: extendedFrame.frame.width - mainWidth,
            height: extendedFrame.frame.height,
          };
        }
        return { ...frames, [extendedFrame.id]: frame };
      }, {});
    },
  };
}
