Hello ,
Thank you for posting your question in the community.
The High Tech Pack assets are in the Object > Home > Living Room > Electronic appliances (67 New objects) and some more in Object > Home > Living Room > Decorations (6 New objects)
I am not sure what furniture item you are referencing in the video and if you can post a screen-shot and describe the object you are looking for I could better respond. Looking forward to hearing back from you.
Kind regards,
Vincent B.
