Declaratively change index of bottom sheet

[novellizator]

My use case is to use it for displaying congratulatory messages when achievements are attained.
Now imagine you have 3 achievements. We cannot have multiple instances of bottom sheets so I wanted to implement it this way:

    {myAchievement && (
      <MyBottomSheet
        index={2}
        achievement={myAchievement}
        onClose={() => {fetchNewAchievement(myAchievement.id)}}
      />
    )}

Where myAchievement refers to the given achievement and is fetched from some (mobx state tree) store. Now the problem is that if I close MyBottomSheet (snap to index 0 =to snappoint 0%), new achievement will render the sheet closed as well. as "2" only refers to the "initial" index.. How would you solve it?
