No, you want to focus more on the large muscles… it is an abbreviated movement to get the body to move the arms.
In an actual swing on the backswing the front arm (left arm for a right handed golfer) will stay straight and the back arm (right arm for a right handed golfer) will eventually bend a little … then on the forward swing the right arm will straighten out and left elbow will bend down (not out that’s a chicken wing). At the very finish on a full swing, most of the time, both arms will bend unless using an advanced shot like holding off the toe from turning over to carve or cut a controlled shot.
