this is the code:

    for item in items:

st.title("SharePoint File Content")

print(token)

    st.text(file_content)
else:

this code is giving me response: {‘error’: {‘code’: ‘itemNotFound’, ‘message’: ‘The resource could not be found.’}}

while it is present in the sharepoint: https://m365x36241825.sharepoint.com/sites/Contoso/Shared%20Documents/Forms/AllItems.aspx?id=%2Fsites%2FContoso%2FShared%20Documents%2FGeneral%2Fdatastax%2Etxt&viewid=30ac4a84%2D14e8%2D4f6e%2D86b4%2D6da6fa8830b3&parent=%2Fsites%2FContoso%2FShared%20Documents%2FGeneral

I have added all the permission in the azure portal.
