Using AI to do keyword extraction, then going further with extracting only nouns?

Hi, I have a dataset that I am working on that is just free text strings, but I have a need to extract the nouns only from the dataset.  For now, I have enabled the "AI Insights" in power query, and have completed a key phrase, then key word extraction, then split the results by deliminator to get all clean words.  I now have a need to somehow extract what would only be words that are considered nouns.  Is there any API or something I can call to do this for me in power query?  Or any other ideas on what to do?

Visualization wise, I have done counts of the words to see frequency and put them in a word cloud, but anything that is not a noun, or considered a noun is pretty much unhelpful and just noise.
