I have this data:

{
    "_id" : ObjectId("5fe9b45d3613f35f9c7fe013"),
    "capitainSide" : "",
    "soldierSide" : "",
    "status" : "creation",
    "type" : "invitations",
    "invitedUsers" : [ObjectId("5fceb82c2917434bb8ef4966")],
    "members" : [ 
        {
            "_id" : ObjectId("5fb71aebc0f0ea402cd8e007"),
            "role" : "capitain",
            "side" : "black",
        }
    ]
}

and I want to get this result:

{
    "_id" : ObjectId("5fe9b45d3613f35f9c7fe013"),
    **"capitainSide" : "black"**
    **"soldierSide" : "white"**
    "status" : "creation",
    "type" : "invitations",
    "invitedUsers" : [ObjectId("5fceb82c2917434bb8ef4966")],
    "members" : [ 
        {
            "_id" : ObjectId("5fb71aebc0f0ea402cd8e007"),
            "role" : "capitain",
            "side" : "black",
        },
        {
            "_id" : ObjectId("5fb71aebc0f0ea402cd8e008"),
            "role" : "soldier",
            "side" : "white",
        }

    ]
}

Actually, I want to update 'capitainSide' field with the value of members array where the role = "capitainSide" in the value of 'side' field, and the same to 'soldierSide' field
