+Since TypeDoc 0.23.26, plugins may also return return an object for more control
+over the displayed link. The returned `caption` will be used if the user does not
+specify the link text.

+The unknown symbol resolver will also be passed the reflection containing the link
+and, if the link was defined by the user, the [CommentDisplayPart](https://typedoc.org/api/types/CommentDisplayPart.html)
+which was parsed into the `DeclarationReference` provided as the first argument.
