Apple Watch, and the remote app with iTunes on a mac

Hello everyone, I am writing to see if any of you have ever used the remote app with iTunes from your Apple Watch.
I recently purchased a series one Apple Watch, and I'm loving it very much!
I was trying to pair my iTunes library on my Mac, to the Apple Watch.
I found the pin code on the Apple Watch, but did not find any place to put it on the iMac.
When I looked at this topic, all it did was have a image of a remote button that I was apparently supposed to click on from with in iTunes, and it said that it would show up whenever the Apple Watch tried to connect to the iTunes library.
I never was able to find any remote button to click two pair of the iTunes library with the Apple Watch remote app. Does anyone have any suggestions? Thank you so much and advance and I think everyone should get an Apple Watch. Just kidding. I do believe that they have their purpose, but I think that they are not for everyone. I do however enjoy mine very much and plan to write an in-depth article on what I use it for but since I have only had it for a week, I'd like to have it a few more weeks before I write this article. All the best.
