Expected Behavior

I want to get the index and style of a textbox in a deeply nested group. The normal text index and style can be obtained normally (the one with blue text)

Actual Behavior

This code doesn't seem to be triggered, is there something wrong with my implementation?

    event.target.getObjects().forEach((group) => {
      fabric.util.addTransformToObject(group, group.group.calcOwnMatrix());

      group.getObjects().forEach((el) => {
        fabric.util.addTransformToObject(el, el.group.calcOwnMatrix());
        if (el.type === "textbox") {
          textboxs.push(el);

          if (el.containsPoint(event.absolutePointer, undefined, true)) {
            const charIndex = target.getSelectionStartFromPointer(event);
            const style = target.getSelectionStyles(charIndex, charIndex + 1);
            console.log(`Character Index in group: ${charIndex}`, style);
          }
        }
      });
    });
