Get a value of item in the array

Question

I have a structure and I want to find a value of token which is a sub-item of access_tokens for a comparing value of tokens. How can I find a token?

{
    "_id" : ObjectId("5aa28846de35244ec439a563"),
    "user" : ObjectId("5a9d53e52d989d2accda2ee5"),
    "refresh_token" : "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJyZWZyZXNoX3Rva2VuIiwianRpIjoiNWE1NDZmOGQtNjBjMy00YmYzLTk0OGQtYjJiM2E5MDU5MWMwIiwib2JqZWN0aWQiOiI1YTlkNTNlNTJkOTg5ZDJhY2NkYTJlZTUiLCJleHAiOjE1MjA2MDQ3MjMsImlzcyI6IlByb25ldCBBUyIsImF1ZCI6IkF1dGhBcGkifQ.sxfUJgFnfMKKtSOLzksfPB-FqQN4ydaKi9YAVZqobK4",

I have class for my access token which is called SubToken and there is a structure for a collection which stored in mongodb and it is called TokenCollection. I reached subtoken (access token) which is sub item of a refresh token it is called Token.

 SubToken res = TokenCollection.Find(new BsonDocument { { "access_tokens.token", access_token } }).FirstAsync().Result.access_tokens.Find(x => x.token == access_token);
