How to make UI Label with Email Text inside it clickable in .Net iOS

Question

I have a .Net iOS application in which I have a Multiline UILabel with an email inside the entire text.

My requirement is to have a Tap on email only and I want to open Email App. For that I registered a Tap and tried to do as per the position but the touch position is not identified properly with below code.

Below is my XIB file.

private void OnEmailLabelTapped(UITapGestureRecognizer recognizer)
    {
        var location = recognizer.LocationInView(AlertMsg);
        var text = AlertMsg.Text;

        // Define the email address to look for
        var emailRange = new NSRange(text.IndexOf(Email), Email.Length);

        if (emailRange.Location == NSRange.NotFound)
        {
            // Email not found, nothing to handle
            return;
        }

        // Create attributed string for the whole text and get attributes
        var attributedText = new NSMutableAttributedString(text);
        var font = AlertMsg.Font;

        // Get the attributes for the email
        var emailAttributedText = new NSAttributedString(Email);

        // Create a Drawing Context to measure
        var textRect = attributedText.GetBoundingRect(
            new CGSize(AlertMsg.Frame.Width, nfloat.MaxValue),
            NSStringDrawingOptions.UsesLineFragmentOrigin | NSStringDrawingOptions.UsesFontLeading,
            new NSStringDrawingContext());

        // Calculate Y position by checking each line
        var currentY = AlertMsg.Frame.Y;
        var emailYPosition = -1.0f; // To be adjusted if found

        // Iterate through the text to find Y position of email
        for (int i = 0; i < emailRange.Location; i++)
        {
            // Simulate getting the char's bounding box
            var charSize = new NSString(text.Substring(i, 1)).GetBoundingRect(
                new CGSize(nfloat.MaxValue, nfloat.MaxValue),
                NSStringDrawingOptions.UsesFontLeading | NSStringDrawingOptions.UsesLineFragmentOrigin, new UIStringAttributes { Font = AlertMsg.Font },
                new NSStringDrawingContext());

            if (currentY + charSize.Height >= location.Y)
            {
                // If the current upper Y with height is in bounds of the tap, set the email position
                emailYPosition = (float)currentY;
                break;
            }
            // Adjust the current Y position for the next character. This crude measurement assumes all characters have similar height.
            currentY += charSize.Height;
        }

        // Fine tune for the email itself
        if (emailYPosition != -1)
        {
            // Estimate Character Width for Email
            var emailRect = new CGRect(
                AlertMsg.Frame.X + emailRange.Location * (textRect.Width / text.Length), // Horizontal position
                emailYPosition,
                emailAttributedText.GetBoundingRect(new CGSize(nfloat.MaxValue, nfloat.MaxValue),
                NSStringDrawingOptions.UsesLineFragmentOrigin | NSStringDrawingOptions.UsesFontLeading,
                new NSStringDrawingContext()).Width,
                font.LineHeight // assume the height is at least line height
            );

            // Check if the tap location is inside the email bounds
            if (emailRect.Contains(location))
            {
                // Handle opening email client
                OpenEmailClient(Email);
            }
        }
    }

How can I achieve this?
