Arrange lots of calls and meetings so that you have regular interaction.
Agree with keeping your camera on, but make sure you don't have anything dodgy in the background.
Keep a pen and pad, bottle of water, headphones, phone/lap top charger nearby - anything you may need when you go into an online meeting as there is nothing more frustrating than having to get up mid call because your pen doesn't work.
Not saying you won't be working, but when you take a break for a coffee/loo/lunch, make sure you are still contactable and in ear shot of your phone/lap top. I had a temp who I couldn't contact when I really needed them. Although they appeared about 15 minutes later, I did wander why they weren't picking up their phone or answering a call on Teams at 9:30am, when they should have been working.
Log onto remote calls a few minutes early, in case you have a problem with the technology.
Give out your mobile/take colleagues mobiles in case you have any problems with remote calls - if your laptop crashes, you can still call/text.
