1. Open the link for joining the co-browsing session as a follower: follower link
2. Fill in the form fields. You can see that the password field is masked by default for the follower, but we've also applied field masking to the "Address" field with our surfly_private attribute.
3. Switch control by clicking the hand icon in the dock. You'll see that the address field disappeared completely on the follower's side and that the submit button got a different color and became unclickable for the follower. This was applied through control dependent appearance.
