OpenAI Authenticator and LLM nodes not seen in KNIME 5.10

KNIME Extensions
,
1

I have installed KNIME 5.10. After installing KNIME AI Extensions I was about to use KNIME Open AI Authenticator and LLM Prompt but I could not find it in my nodes repository. I have tried the following:

  1. Download the zip file and use the executable again and repeat the installation of the extension.
  2. Uninstalled and installed KNIME AI Extensions but no use.
  3. Uninstalled the KNIME AI Extension, Drag and dropped the node from the KNIME Community Hub and installed it again, still error.

  1. Uninstalled the KNIME AI Extension, Drag and dropped the entire OpenAI workflow and installed it again, no success.

I am using Windows 10 and I just use the zip file since our office do not allow installations.

Here is the error message from the workflow:
