Take the easy way out. Just install "Element X", a free Matrix client, on your phone, desktop or more to protect your client's privacy with fully encrypted communications, groups, chat, VoIP, file sharing and more.
Do _not_ use Discord or any other commercial communication platform for medical communication. European governments, militaries and ordinary citizens use Matrix. It is open source and covers a wide range of features for secure, real-time communication. There are lots of other good features, but that would be too much for now.
Although Mastodon is great for sharing public information and a friendly place to hang out, it doesn't (yet) encrypt communications as required and the groups feature is still in development.
