Import demo failed

I have installed the oceanwp theme and I would like to import this demo to modify my page from it:
https://megagym.oceanwp.org/
I have installed the “ocean demo import” plugin, but the “Theme Panel” section that shows the video from the oceanwp website does not appear in my menu.
Can someone help me install that demo?
Thanks a lot!
