+If you want to configure a telegram bot webhook, you need to get a middleware from `TelegrafProvider` for connect it in your `main.ts` file.
+ 
+To access it, you must use the `app.get()` method, followed by the provider reference:
+```typescript
+const telegrafProvider = app.get('TelegrafProvider');
+```
+
+Now you can connect middleware:
+```typescript
+app.use(telegrafProvider.webhookCallback('/secret-path'));
+```
+
+The last step is to specify launchOptions in `forRoot` method:
+```typescript
+TelegrafModule.forRootAsync({
+  imports: [ConfigModule.forFeature(telegrafModuleConfig)],
+  useFactory: async (configService: ConfigService) => ({
+    token: configService.get<string>('TELEGRAM_BOT_TOKEN'),
+    launchOptions: {
+      webhook: {
+        domain: 'domain.tld',
+        hookPath: '/secret-path',
+      }
+    }
+  }),
+  inject: [ConfigService],
+});
+```
