How to get array filters to work with eventuous mongo projector

How to get array filters to work with eventuous mongo projector? I got this use case where I want to traverse through an array and update a variable.
For example in the below mongo document, I want to set HumanId 2 -> IsMainContact to true and everything else to false

[
   {
        "HumanId": "1",
        "IsMainContact": true
    },
   {
        "HumanId": "2",
        "IsMainContact": false
    },
    {
        "HumanId": "3",
        "IsMainContact": true
    }
]

I can probably do something like this,
.Set("Contacts.$[y].IsMainContact", true)

But there is no way for me to set array filter for y like this,

var arrayFilters = new List<ArrayFilterDefinition>
{
    new JsonArrayFilterDefinition<BsonDocument>("y.HumanId", 2))
};

I was able to do this using Filter and $ operator, but this way, we can't use lambda expressions. Using the typed variant form provides compile-time safety and IDE can provide refactoring support, this is my current approach in the image below,
