This code can’t seem to access text inside shapes, is there a way how to?

from docx import Document

doc = Document('template.docx')
replace_word = {'Captain': 'Gerard B. Geronimo'}
for word in replace_word:
    for p in doc.paragraphs:
        if p.text.find(word) >= 0:
            p.text = p.text.replace(word, replace_word[word])

doc.save('note_demo.docx')

I tried everything that I could find on the internet but couldn’t find anything.
