How to customize invitation in mobile application


From what I see in the code, we can define inviteServiceUrl which will be used to send invitations to a custom service. This is great! Here are some questions:

  1. According to what I understand from the code, this is also used in the mobile application, can someone confirm this? ie the web config.js file is used in the mobile app when opening a conference?
  2. If 1 is true, how can (or is it possible) I update/configure to allow user to fill emails in the form instead of awaiting for phone number?

Thanks a lot
