sequelize user表自关联多对多查询怎么用?

Question

用户表user: id name
用户关注表follows: userId followerId

User.belongsToMany(User, {
    through: "Follows", 
    as: "follower"
});

问题:

现在可以通过User查询到当前用户的关注者

await User.findOne({
    where: {
        username
    },
       include: ['follower'] 
});

如何查询当前用户关注了谁?
