Flutter: Can't open telegram channel from URL_LUNCHER – Telegram API

I want to direct open to telegram channel using url_luncher from my flutter app.
currently, I can open the telegram app but it does not direct to the channel.

Is there any configure would need to achieve this?

GestureDetector(
    onTap: () async {
      var url = Uri.parse("tg://t.me/channel_name");
      if (await canLaunchUrl(url)) {
        await launchUrl(url);
      }
    },
    child: ListTile(
      visualDensity: const VisualDensity(vertical: -4),
      minLeadingWidth: leadingTxtSpace,
      leading: const CircleAvatar(
        radius: 15,
        backgroundColor: Colors.blueAccent,
        child: Icon(Icons.telegram_outlined, color: Colors.white),
      ),
      title: Text(
        "Telegram",
        style: Theme.of(context).textTheme.bodySmall,
      ),
    ),
  ),

    You can adapt the example yourself

    IconButton(
                          onPressed: () async {
                            await launch(
                              "https://t.me/Your link",
                              forceSafariVC: false,
                              forceWebView: false,
                              headers: <String, String>{
                                'my_header_key': 'my_header_value'
                              },
                            );
                          },
                          icon: Icon(
                            FontAwesomeIcons.telegram,
                            color: Colors.blue,
                          ),
                          iconSize: 45,

    In older version its working fine

    url_launcher: ^6.0.12
minSdkVersion 21
targetSdkVersion 30
sdk: ">=2.12.0 <3.0.0"

    After upgrading SDK & Packages facing same issue. app opened but not navigate to specific chatting screen so i found solution for whatsapp & telegram app.

    url_launcher: ^6.1.6
minSdkVersion 21
targetSdkVersion 33
sdk: ">=2.12.0 <3.3.6"

    add few things inside <queries> in AndroidManifest.xml

    <queries>
                       
     <!-- Place inside the <queries> element. -->
                    <intent>
                     <action android:name="android.intent.action.VIEW" />
                        <category android:name="android.intent.category.BROWSABLE" />
                        <data android:scheme="https" />
                    </intent>
                    
                    <package android:name="com.whatsapp" />
                    <package android:name="org.telegram.messenger" />
</queries>

    in launchURL you need to pass mode parameter explicitly with value: LaunchMode.externalApplication like this:

    try {
    "Launch URL: $url".printLog();
    if (!await launchUrl(Uri.parse(url), mode: LaunchMode.externalApplication)) {
      showToast(sSomethingWrong);
    }
  } catch (ex) {
    "Could not launch url $ex".printLog();
 }

    Used URL in my app

    String sURLTelegram = "https://t.me/user_name";
String sURLWhatsapp = "whatsapp://send?phone=";
