Gmail, Gmeet and the occasionally the instant chat box built into Google accounts. Definetely not a comprehensive stack but we intentionally try to messy communications so we can spend more time focusing on the work and regroup when necessary over call.
My team is mainly in Slack's virtual world, and we are also using Zoom for video calls.. :) But I must say that I have a great experience with Teams as well :) Have you try it?
We mostly rely on asynchronous mode of communication like Google Hangouts, and our very own product, Vmaker. However, every day we have stand-up meeting on Google Meet.
