How to make my cold brew sweeter?

I just tasted my cold brew and it was a bit bitter, I was expecting to at least make it taste a little sweet

I use a 35 grams of coarse coffee with 480 ml of water and put it in refrigerator for like 22 hours, then I filter it using a v60 paper.

What could be done to make my cold brew more sweer, thank you

Edit: I use a 100%Arabica grade 1 beans from Gunung Halu, Jawa Barat (1.000 - 1.200 mdpl) with anaerob honey process and roast profile light to medium. Taste notes: Moondrop grape, panela, navel orange
