Firestore update nested data [duplicate]

Question

i am stuck with a problem with firebase (with Vue). I want to add the user id to a specific map (yes, maybe or no) when the user presses a specific button. But Im having trouble add/update the data because its nested. Here is my data structure in Firestore

I want to add the user id in a map, something like this:

dates: { [ 0: { yes: [userId1, userId2] } ] }

Does anyone can help me pushing the user ids into the arrays?

Unfortunately, right now it is not possible to update a specific element of the array. You can add new items or remove them - look here. But I would consider a little change in the approach and create a collection called dates in which you can define documents, which will contain yes, no, maybe arrays, which can be easily updated - in the way mentioned before.
