Not able to cluster Conv1DTranspose layer

Hi,
Describe the bug
A clear and concise description of what the bug is.

Getting below error while trying to cluster the convolution layers. Is Conv1DTranspose clustering is possible or not? Can anyone suggest how to solve this.

Please initialize Clusterwith a supported layer. Layers should either be aClusterableLayer instance, or should be supported by the ClusteringRegistry. You passed: <class 'keras.layers.convolutional.Conv1DTranspose'>

System information

Code to reproduce the issue
Provide a reproducible code that is the bare minimum necessary to generate the
problem.

import tensorflow as tf
import tensorflow_model_optimization as tfmot

cluster_weights = tfmot.clustering.keras.cluster_weights
CentroidInitialization = tfmot.clustering.keras.CentroidInitialization

time_dat = tf.keras.layers.Input(batch_shape=(1, 16000))
x1 = tf.keras.layers.Conv1D(10, 256, 64, padding = "valid",use_bias=False)(tf.expand_dims(time_dat, axis=-1))
x2 = tf.keras.layers.Conv1DTranspose(1, 256, 64, padding = "valid",use_bias=False)(x1)
model = tf.keras.models.Model(inputs=time_dat, outputs=[x2])

clustering_params = {
  'number_of_clusters': 50,
  'cluster_centroids_init': CentroidInitialization.LINEAR
}

def apply_clustering_to_dense(layer):
  if isinstance(layer, tf.keras.layers.Conv1D):
    return cluster_weights(layer, **clustering_params)
  return layer

clustered_model = tf.keras.models.clone_model(
    model,
    clone_function=apply_clustering_to_dense,
)

Additional context
Add any other context about the problem here.

Start by running the provided TensorFlow Model Optimization reproduction with Conv1DTranspose and review the ClusterableLayer and ClusteringRegistry support named in the error. Determine whether Conv1DTranspose is intended to be supported; done means the support status and expected clustering behavior are clear and the reproduction no longer produces the reported unsupported-layer error.
