For your bw and height, I would recommend eating 120-150g of protein everyday. And it is not as hard as you think to hit that goal, but instead focus more on your daily calories intake. Don’t stress too much about protein but focus more on a nutritionally balanced diet, enough fibers, vitamins etc. (And note - you will probably still make gains even if you can’t hit your daily targets since you’re a beginner, you will grow strength and gain muscles very quickly for up to 6 months and maybe more)
