❔ Connection Timeout argument passed doesn't work for a SqlConnection

<add name="DatabaseServerInstance" 
     connectionString="Server=xx.xx.x.xx; Database=db; User Id=user; Password=pass; TrustServerCertificate=true; Connection Timeout=2;" />

public class SqlPusher
{
    private static SqlCommand command = new SqlCommand();
    private static string connectionString = ConfigurationManager.ConnectionStrings["DatabaseServerInstance"].ConnectionString;

    public Boolean TestConnection()
    {
        using (SqlConnection connection = new SqlConnection(connectionString))
        {
            try
            {
                connection.Open();
                return true;
            }
            catch (SqlException)
            {
                return false;
            }
        }
    }
