how to create Time distributed layer

Hi, i try to create a time distributed layer for my lstm encoder decoder, which i make use of timedelaynet. But whenever i make use this, i get the error because it is the network instead of layer. May i know if there is anywhere to create time distributed layer. Thank you

layers=[...
    sequenceInputLayer(numInFeatures)
    lstmLayer(numEnUnits,"OutputMode","last")
    repeatVectorLayer(30)
    lstmLayer(numDeUnits)
    timedelaynet(30,numDenseUnits)
    timedelaynet(30,numOutFeatures)
    regressionLayer];

%% this is the error that is gotten
Cannot convert from 'network' to 'nnet.cnn.layer.SequenceInputLayer'.
