I worry that teachers new to online are so focused on live sessions because they think that:

a) what happens when they're present is more important than what happens when they're absent

b) they only need to be present during live sessions.

Both a and b are false.

What students do outside live sessions is more important. This needs self-regulation, but also co-regulation. Design meaningful activities and make live sessions support these, not vice versa (flip the flipped classroom again). Design non-live conversations into the activity.

This is key to building community: engagement, presence & contact continues outside live sessions. Live sessions focus on what students are doing, not the teacher's agenda. Multiple ways to contribute at different times. Opportunities to express themselves and be creative.
