Thanks for the exact description of the problem.
I can't call the fortnite skin, hard to understand?
The Honor Guard Skin has been deactivated. He will be available again in 1-2 weeks. It is quite normal that you can't get it for yourself. If you know a little bit of English, you are welcome to drop by on the homepage. There's also the instructions on how you can get the skin.
In addition, you can ask questions at any time by clicking on your question, then there on the 3 points and then there's "ask again ask". This will save you the trouble of writing the question again.
What is the homepage?
I'm sorry. I thought I wrote the link. Here it is: https://www.hihonor.com/global/events/honor-view20-fortnite-outfit-honor-guard/
The page is currently offline, but as soon as the skin is activated again, there's the instructions.
Now it is there but it can't ring
That is normal. The skin is still disabled.
