How to remove array element from an array of arrays which also has non array elements

Question

I am working on a multiplayer game and I have a room array with the following layout (I added comments for better understanding):

Room_Array
[
    [
        "Room_0",   // room name
        10,         // max people
        "Random",   // room type
        [           // now arrays of players follow
            [
               1,     // ShortID
               123,   // position X
               234,   // position Y
               10     // angle
            ],
            [
               2,
               123,
               234,
               10
            ],
            [
               3,
               123,
               234,
               10
            ],
        ]
    ]
    // here other rooms are created with the same layout as Room_0 when the max people is reached
]

How would I go around to remove the whole array of the player with ShortID = 2? in case he disconnects?

So the desired result would be:

Room_Array
[
    [
        "Room_0",   // room name
        10,         // max people
        "Random",   // room type
        [           // now arrays of players follow
            [
               1,     // ShortID
               123,   // position X
               234,   // position Y
               10     // angle
            ],
            [
               3,
               123,
               234,
               10
            ],
        ]
    ]
]

I tried the following code and in the console log it showed me the elements of the array I need to splice, so 2, 123, 234, 10. The commented splice resulted in error unidentified element 1.

for (var i = 0; i < Room_Array.length; i++)
{
    if (Room_Array[i][0] === PlayerObject[socket.id].RoomName)
    {
        for (var j = 0; j < Room_Array[i][3].length; j++)
        {
            if (Room_Array[i][3][j][0] === PlayerObject[socket.id].ShortID)
            {
                console.log("Array to splice: " + Room_Array[i][3][j]);
                //Room_Array.splice([i][3][j], 1); // error unidentified 1

            }
        }


    break;
    }
}

Here is a working solution that mutates the initial array.

const Room_Array = [
    [
        "Room_0",   // room name
        10,         // max people
        "Random",   // room type
        [           // now arrays of players follow
            [
               1,     // ShortID
               123,   // position X
               234,   // position Y
               10     // angle
            ],
            [
               2,     // ShortID
               123,   // position X
               234,   // position Y
               10     // angle
            ],
            [
               3,
               123,
               234,
               10
            ],
        ]
    ]
];
    
function removeUser (array, id) {
  array.forEach(room => {
    const [roomName, maxPeople, roomType, players] = room;
    const index = players.findIndex(([shortId]) => shortId === id);
    if(index > -1) {
      players.splice(index, 1);
    }
  });
}

removeUser(Room_Array, 2);

console.log(Room_Array);
