I wish my company had an official unofficial chat app other than Teams. Many people will find what other apps people are already on, and then use those apps to avoid using Teams. Some are on Slack, others Discord, some Signal, and we have various other chats going on in those apps because attachments, code snippets, and other functionality is so inconvenient on Teams. Anything official that needs to be shared and recorded for the company or requires widespread notification is through Teams, but then individuals are all using their own apps and management thinks Teams satisfaction is above 90% according to some surveys that no one I've talked to has filled out.
