+Beware! This script will make you reply to ALL new messages in every single supergroup you are in.
+Make sure you add an extra check to filter them:
+
+# Filter Supergroups by ID
+if message.to_id.channel_id == MY_SUPERGROUP_ID:
+    ...
+
+# Filter Supergroups by Username
+if chats[message.to_id.channel_id].username == MY_SUPERGROUP_USERNAME:
