ValueError: Unknown layer: Addons>ESN

I have trained the following model:

model = Sequential(name='ESN_NE')
        model.add(InputLayer((timesteps, input_dim), name='Input_Layer'))
        model.add(ESN(units=200, activation=['tanh'], name='ESN'))
        # model.add(Flatten())
        model.add(Dense(units=100, activation=['tanh'], name='1_Dense'))
        model.add(Dense(units=48, activation=['tanh'], name='2_Dense'))
        model.add(Dense(units=24, activation=['tanh'], name='Output_Layer'))
        model.compile(optimizer='adam', loss='mean_squared_error')

And saved it in a .hdf5 file.

Now i am trying to load it to use my test set:

model = load_model('C:/.../ESN_model.hdf5')

But i am getting the following error:

How can i fix this?
