Hi Dev
Returning to a very interesting topic, I share with you the open source tool used officially by the ietf, since it is open source where all the workgroups are and that visually is similar to slack in all its functions.
compared to discord or ms teams it is more simplified but with the necessary tools and above all it avoids creating whatsapp groups since the point of whatsapp is to avoid sharing personal numbers.
tools like loomio were interesting to use some years ago, now the cost is quite prohibitive. some time ago a test was made with ryver but everybody abandoned it.
Additionally, it has an option to request the standard plan at no cost to non-profit organizations which allows a growth in the use of the tool over time.
best regards
