How to get path on datastore from input dataset instead of pathOnCompute(mount path)

I would like to get the datastore path e.g. datastores/storepath/paths/shares/...
instead of pathOnCompute from my inputDataSet. What API should I use?
I tried the following but none of them work:

paths = input_dataset.to_path() //the to_path() only get the file name list, it doesn't contain the path

get_details() only contains pathOnCompute as well

Thanks for your input
