How do I add a newline after DocumentationCommentTriviaSyntax?

var methodDeclaration = SyntaxFactory.ParseMemberDeclaration("   public   void Hello3<T, H, E, G>() where T : class, E, new() where E : notnull, IList<E>, IEquatable<E> where H : unmanaged, allows ref struct where G : unmanaged  {    }") as MethodDeclarationSyntax;

var interfaceListType = SyntaxFactory.ParseTypeName("IList<T>");
var indexType = SyntaxFactory.ParseTypeName("Index");

var crefParameters = SyntaxFactory.SeparatedList(
    new[] {
        SyntaxFactory.CrefParameter(SyntaxFactory.ParseTypeName("T")),
        SyntaxFactory.CrefParameter(SyntaxFactory.ParseTypeName("T"))
    }
);

var nameMemberCref = SyntaxFactory.NameMemberCref(indexType, SyntaxFactory.CrefParameterList(crefParameters));
var indexerMemberCref = SyntaxFactory.IndexerMemberCref(
    SyntaxFactory.Token(SyntaxKind.ThisKeyword),
    SyntaxFactory.CrefBracketedParameterList(crefParameters)
);

var qualifiedCref = SyntaxFactory.QualifiedCref(interfaceListType, indexerMemberCref);
XmlCrefAttributeSyntax xmlCrefAttribute = SyntaxFactory.XmlCrefAttribute(qualifiedCref);

DocumentationCommentTriviaSyntax documentationComment = SyntaxFactory.DocumentationCommentTrivia(
    SyntaxKind.MultiLineDocumentationCommentTrivia,
    SyntaxFactory.List(new XmlNodeSyntax[]
    {
        SyntaxFactory.XmlNewLine(""),
        SyntaxFactory.XmlEmptyElement("inheritdoc").AddAttributes(xmlCrefAttribute)
    })
);

methodDeclaration = methodDeclaration.WithLeadingTrivia(SyntaxFactory.Trivia(documentationComment));
Console.WriteLine(methodDeclaration.NormalizeWhitespace().ToFullString());
