deep link windows button

so, I registered my deep link on widows and is working perfectly
Thanks @Anonymous if I type demy-ia//e it will open the app but the problem comes when sending the email

 private static string GenerateHttmlTemplate(string roomName, string meetingLink, string userName, DateTime? dateTime = null) {
     return $@"
         <html>
         <head>
             <style>
                 /* CSS for the button */
                 .button {{
                     background-color: #5C3E88; /* Button background color */
                     color: white; /* Text color */
                     text-decoration: none;
                     padding: 10px 20px; /* Padding around text */
                     border-radius: 5px; /* Rounded corners */
                     display: inline-block;
                 }}
             </style>
         </head>
         <body>
             <p>Here are the meeting details:</p>
             <br> <!-- Add a line break -->
             <p><strong>Meeting Name:</strong> {roomName}</p>
             <p><strong>Teacher Name:</strong> {userName}</p>
             <p>Click the button below to join the meeting:</p>
             <p><a class='button' href='{meetingLink}'>Join</a></p>
         </body>
         </html>";
 }

 public static async Task SendEmail(ObservableCollection<User> users, string roomName, User? user, DateTime? dateTimeMeeting) {

     try {
         var meetingLink = string.Empty;
         using(var smtpClient = new SmtpClient("smtp.gmail.com")) {
             smtpClient.Port = 587;
             smtpClient.Credentials = new System.Net.NetworkCredential(Constants.EMAIL, Constants.APP_PASSWORD);
             smtpClient.EnableSsl = true;
             smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;



             if(DeviceInfo.Platform == DevicePlatform.WinUI) {
                 string protocol = "demy-ia";
                 meetingLink = $"{protocol}://{roomName}";
             } else {
                 meetingLink = $"{Constants.BASETTING_URL}{roomName}";
             }

             Console.WriteLine(meetingLink);

             foreach(var recipient in users) {
                 var mail = new MailMessage() {
                     From = new MailAddress(Constants.EMAIL),
                     Subject = "DemyIA meeting",
                     IsBodyHtml = true,
                 };

                 var body = GenerateHttmlTemplate(roomName, meetingLink, user!.Name, dateTimeMeeting);

                 mail.Body = body;

                 // Add the recipient to the message
                 mail.To.Add(recipient.Email);

                 // Send the email asynchronously and await the task
                 smtpClient.Send(mail);
             }
         }

         Console.WriteLine("Email sent successfully to the SMTP server.");

     } catch(Exception e) {
         await Console.Out.WriteLineAsync(e.Message);
     }
 }

If I send an email to from an Android, it will generate. https://demy-ia.daily.co/e and because this is a valid URL, the button will appear.

but for windows, we have to modify the URL, to make it open my app. demy-ia://e
this is not a valid URL. so it will not show

and with this I will be able to adjust the link hen the app opens, and send it to a webview in Maui
