How to get entity by its UUID (1.20.1)

ok so im trying to make a telescopic sight block, ive heard i need a entity to be used as the camera/renderer, i can get the entity spawning and UUID saving functional, but i cant seem to find a way to get the entity back with its UUID
ive searched a lot but all the methods i found seems to use the World class, which doesnt seem to be in 1.20

saving (zombie is a placeholder)

if (!level.isClientSide()){
            BlockEntity BE = level.getBlockEntity(pos);
            if(BE instanceof ScopeEntity blockEntity){
                Entity entity = new Zombie(EntityType.ZOMBIE, level);
                entity.moveTo(pos.getX() + 0.5f, pos.getY() + 1, pos.getZ() + 0.5f);
                level.addFreshEntity(entity);
                blockEntity.saveID(entity.getUUID());
            }
        }
