Micromanagement isn't about frequency of contact so much as the amount of control the worker has over their work. The biggest micromanager I ever worked for would forget I existed for days or a week at a time, only to come in tell me to throw out hours of work and do very specific, arbitrary things instead because he just liked it better a different way. The most hands-off boss I've ever had would drop by for a chat almost every day, but mostly just to get thoughts on overall direction and discuss ideas he was mulling.
We could speak daily and not have it be micromanagement. There is just not anything to speak about most days. We did good morning in the chat for a while, but that just died after the first few weeks.
"Speaking" doesn't imply "managing" in a negative sense. It's simply a medium to convey information. Is it micro managing to see a direct report in the hallway or at lunch and casually say "Hey, Alice was saying that we could really use a new X, what do you think about that?" That level of discussion would very rarely occur over Slack or during a scheduled 1:1.

Out of curiosity, why? I have this kind of discussion in Slack fairly often, sometimes in a (smaller) channel, sometimes in direct messages (occasionally with >2 people in in). A quick conversation about an idea, where people can respond as time permits, seems fairly optimal for Slack.
