- I don't implement all the possible type of messages because 
1. Too complex and make the UI very clustered
2. I don't think those messages are frequently used.

- I initially wanted to make send catalog template message task.
However, sending catalog template requires a real phone number which is
not connected to any other WhatsApp account. For now, I will be skipping
send catalog template task since I don't have the necessary phone number
to test it.
- There is no read message task because in order to read/receive
message, need to use webhook.

Here is a document to explain more about the component
