Override or customize the default behavior of "longpress mailto:"

Question

I'm currently developing an email application and want all mailto links to open through my application, and not the default Apple Mail application.

For example, I have a link like this

<a href="mailto:[e-mail]\>mailto_test</a>

in a UIWebView or UITextView (it doesn't matter which one has similar behavior).

When I disable this link, iOS will show UIAlertController with three parameters:

The first option, New Message, will open the Mail app by default. So my question is how to override this behavior? How can I get this feature to run my own email application?

    options:[.documentType: NSAttributedString.DocumentType.html],
    documentAttributes: nil)

textView.attributedText = attrStr
view.addSubview(textView)

textView.isEditable = false
textView.dataDetectorTypes = .link
textView.delegate = self
