I have a requirement to create a Group with a set of Mobile numbers (without Creating the Contact in the Mobile Device).

1. I have Created the Jid objects for all the Mobiles numbers
2. I have Created the Contact objects from all the Jid objects in the step # 1 and added to WhataAppApi.store().addContact()
3. Now, i have tried to add the contacts created in the # 2 to the Group using WhataAppApi.addGroupParticipants(jidGrp, contact1, contact2, ...);

We don't get any errors, but the contacts are not getting added to the Group.

How can we create a Group with a set of Mobile numbers (without Creating the Contact in the Mobile Device)?

Thanks in advance !!!
