If most of these people dont't use Slack yet i wouldn't push it. Non-technical people tend to have some resistance towards these new technologies especially in their free time. I would start with assessing which messaging tools they are already using and see if one of that feeds your needs. While Slack (or other similar tools like Discord, Teams, Matrix) would be theoretically suitable, it doesn't help when no one uses it. A set of WhatsApp/Signa/Telegram Groups for different kind of topics might be the better solution. If you are deciding towards a new Tool that most of the people aren't familiar, I'd suggest to organise a little install party to get everyone ready to use the new tool and to overcome the potential initial scepticism and to gain momentum. Also make sure to define a concrete cut-over date to avoid creating just an additional channel.
