Find all MongoDB documents from a list of ids using `in` operator

i am trying to find documents in collection by ids. Most of the suggested answers use C# class that matches with the document. something like here

var filter = Builders<Product>.Filter
 .In(p => p.Id, productObjectIDs);

i don't have corresponding C# class, so i am using BsonDocument

public async Task<IEnumerable<BsonDocument>> GetData(IEnumerable<int> documentIds)

 var collection = _mongoDatabase.GetCollection<BsonDocument>("mycollection");

 // how do set filter here
 var filterBuilder = Builders<BsonDocument>.Filter.In<int>("???????", documentIds);

 var projection = Builders<BsonDocument>.Projection
 .Include("_id")
 .Include("status")
 .Include("units");

 var result = await collection.Find(filterBuilder).Project<BsonDocument>(projection).ToListAsync().ConfigureAwait(false);
 return result;

I am not sure how do i set filter with in operator?
