Send Whatsapp message to a list

MIT App Inventor Help
1

Hi, I have an app to book tennis courts for my club.
Now I would like to insert the possibility to send a Whatsapp message to all Members to look for a partner. I have a table with their phone numbers and I wish I could send the same message to everyone. I know how to make a message from App Inventor. But is it possible to send it to all the numbers on the list?
Thanks

With this extension you can send messages to several users, but it is necessary to choose one by one. It is not automatic.

I thought to put the phone number in a cycle and launch the activity several times but it doesn’t work …
