jupyter-tabnine: jupyter-tabnine doesnt work at all after installation

I followed instruction but failed. Everything seems to be installed pretty well (I see it nbextension menu enabled), but doesn’t work at all, in addition it broke old default autocompletion, but started to work afain after disabling this extension. What can I do to make it work?

Below info that I did:

!jupyter nbextension install --py jupyter_tabnine
!jupyter nbextension enable --py jupyter_tabnine
!jupyter serverextension enable --py jupyter_tabnine

    To initialize this nbextension in the browser every time the notebook (or other app) loads:
    
          jupyter nbextension enable jupyter_tabnine --py
