My main group of friends with whom I play videogames on a daily basis is on Telegram. We use voicechat and stream our gameplay on discord for others to watch/comment in a more private setting (other tools are too public). I wrote a bot that notifies on the telegram group whenever someone starts a stream on discord so others jump in and join the game/stream. Discord shares which game/activity through their API so we know exactly what someone is playing. I also add some personalized randomized spice depending on who is streaming and what they are playing to the telegram bot messages so we can laugh about it.
Whenever the bot has gone down (I turned off the home server or whatever) my friends complain, so I know the bot is fulfilling its purpose :)
