Can't set new value inside updateOne hooks in Mongoose while updating

I have a user schema that when i add a new one to the database it hashes the password in the pre(save) hook but i want to do the same while updating but it saves the plain password instead of hashed one

this works fine while creating new record

UserSchema.pre('save', async function (done) {
  if (this.isModified('password')) {
    const hashedPassword = await Password.hash(this.get('password'));
    this.set('password', hashedPassword);
  }

  done(null);
});

but this didn't work fine

UserSchema.pre('updateOne', async function (done) {
  const hashedPassword = await Password.hash(this.get('password'));
  this.set('password', hashedPassword);

  done(null);
});

NOTE: there are no errors in the console

mongoosejs.com/docs/middleware.html#pre

if you define pre('updateOne') document middleware, this will be the document being updated. That's because pre('updateOne') document middleware hooks into Document#updateOne() rather than Query#updateOne(), so it should be

schema.pre('updateOne', { document: true, query: false }, function() { console.log('Updating'); })
