What is wrong with this code? It should return [4, 5], however it returns [1, 2, 3, 4, 5]

const numbers = [1, 2, 3, 4, 5];

function applyOperation(n) {
    return new Promise((resolve, reject) => {        
        setTimeout(() => resolve(n), 2000)
    });
}

const res = numbers.filter(async num => {
    
    return await applyOperation(num) > 3;
});

console.log(res);
