Can try this. Hope resolve your issue

public struct MarkdownUI2: UIViewRepresentable {
  private let markdownView: MarkdownView
  @Binding public var body: String
  
  public init(body: Binding<String>, css: String? = nil, plugins: [String]? = nil, stylesheets: [URL]? = nil, styled: Bool = true) {
    self._body = body
    self.markdownView = MarkdownView(css: css, plugins: [], stylesheets: stylesheets, styled: styled)
    self.markdownView.isScrollEnabled = false
  }
  
  public func onTouchLink(perform action: @escaping ((URLRequest) -> Bool)) -> MarkdownUI2 {
    self.markdownView.onTouchLink = action
    return self
  }
  
  public func onRendered(perform action: @escaping ((CGFloat) -> Void)) -> MarkdownUI2 {
    self.markdownView.onRendered = action
    return self
  }
}

extension MarkdownUI2 {
  
  public func makeUIView(context: Context) -> MarkdownView {
    return markdownView
  }
  
  public func updateUIView(_ uiView: MarkdownView, context: Context) {
      self.markdownView.load(markdown: self.body)
  }
}

    var onTouchLink: (URLRequest) -> Bool = { _ in true }

    // you can omit some parameters
    public init(text: String, css: String? = nil, plugins: [String]? = nil, stylesheets: [URL]? = nil, styled: Bool = true) {
        self.text = text

    // should delay when first load, because it takes long time before webview load main.js completely.
   // you can optimize it when necessary, such as "(uiView.intrinsicContentSize.height==0 ? 1.0:0.0)"

        uiView.onTouchLink = onTouchLink
        DispatchQueue.main.asyncAfter(deadline: .now() + 1.0) {
            uiView.show(markdown: self.text)
        }
    }
}

        then {

    }

        then {
