How do you keep slack online 🟢 when away for 1-2 hours?

Because of compliant stuff, screen would go off if no interaction for more than 30 minutes. I start around 9 and definitely work 4-5 hours with focus but I want to go for exercise or gym at 4 and don’t wanna do my slack offline!! It doesn’t really matter, but I know most of us definitely don’t work 8 hours straight! I know some folks who would keep weight on spacebar and open a blank word doc which will keep the screen on😛 in windows! But in mac, it doesn’t really work! Any tricks to keep online while you are away in last hour working out??😜 PS: no one cares, but I don’t wanna be offline TC: 200k #misc #remote #slack
