title: How to get User ID by InstaSharper
body: <p>I'm learning InstaSharper, but I can't understand how to Follow/Unfollow user. Because <code>UnFollowUserAsync</code> requires UserId. Can you tell me please how to get User's ID, or maybe there are other ways to follow/unfollow users. </p>
  
  <p>Thanks in advance</p>
