iMac powering down / sleeping and Roon

Apple Folk ... how to keep iMac awake?

I’m going to try using an external hdd to hold my music, instead of my NAS. I hear that will speed up finding new music, right? But my 2019 Mac keeps falling asleep. I checked the box that tells it not to, and enabled network access, doesn’t seem to work. Any thoughts ? Am I doing something wrong? The iMac seems to work well as a core but I want it always available without having to wake it up. Thanks!

Amphetamine/caffeine?
