export const schedules = [
    { unit: "hour", quantity: 6 },
    { unit: "day", quantity: 1 },
] as const;

const getOffsetName = (schedule: (typeof schedules)[number]) =>
    `${schedule.quantity}_${schedule.unit}` 

Why is the return type of getOffsetName "6_hour" | "6_day" | "1_hour" | "1_day" instead of "6_hour" | "1_day"?
Is there any way to make typescript more specific in this case?
