Do not receive notification when invitee rejects an invite to a call

Describe the issue
When inviting a user to an already established call, I do not receive respected event when he/she rejects the call, despite that I see it in logs.

Code Snippet

_endpoint.TeamsClient.OnNotificationProcessed += (r) => {
                switch (r.Notification.ChangeType) {
                    case ChangeType.Deleted:
                        var extracted = r.Notification.ExtractResouceData();
                        break;
                    default:
                        break;
                }
            };

 var operation = await (_botCall).Participants.InviteAsync(
                new List<InvitationParticipantInfo>() {
                    new InvitationParticipantInfo() {
                        Identity = usertocall,
                    }
                },
                cancellationToken
            );

Expected behavior
Should get the following data when I use "extracted " from above code:

Start with the OnNotificationProcessed callback and the Participants.InviteAsync call shown in the report, then compare them with the logged Deleted notification for the invite operation. Trace why the callback reports no registered handler while the notification is later logged, and verify that a rejected invite exposes the expected resultInfo with code 603 and a Decline message.
