Hey there,
I am really sorry for the delay of this reply as it is a weekend for us here.
May i know which kind of link you referring? It would be best if you can provide us some of the screenshot regarding this so we can better understand on this.
By the way, if you are referring when someone share a link in the story link, but this link automatically set to nofollow attribute, then you can check from your
