Can not a node to a Component

Hi,

I am trying to add a Conda Environment Propogation node into one of the components contained in the Time Series workflow (01AccessingTransformingandModelingTimeSeries)

I am doing this as I have an issue with the Python Script node in the component and am looking to use the information provided in another post that shows adding the Conda node to drive the environment.

However when trying to add the node nothing happens, I have tried with other nodes and the same happens. Are these components locked as Read Only and if so is there a way to change it so we can amend the component ?

Thanks
