I tried that a long time ago with teamspeak, and then discord, but my friends are not big users of these tools and so it didnt work. Discords do too much. If whatsapp could do this it could work
Telegram feels like it can definitely do such stuff and I found in my opinion that its way easier to host telegram bot on cloudflare than it is on discord so theoretically you could even have it as a cf worker with a deploy on cf button so as to even people who don't know too much about deploying could use it.
