Rt - CLI group edit membership

RT Users
1

Hi,

I failed to edit group memberships via cli. ENV at end of mail.

  1. check who is member of a group – so far, everything work as aspected

    wulf@host ~ $ rt show group/mygroup
  id: group/116
  Name: mygroup
  Description: mygroup

Members: Member 1 <member.1@mail.com>,
         Member 2 <member.2@mail.com>,
         ... 
         Member 20 <member.20@mail.com>

  2. add a member (already existing and privileged user)
    I didn’t find information how to define the new user
    mail address: member.1@mail.com
    or
    id: 12345
    or
    as listed: New Member new.member@mail.com

    all of them are acceptet but non of them work.

    wulf@host ~ $ rt edit group/mygroup add members=new.member@mail.com
  id: group/116
  Name: mygroup
  Description: mygroup

Members: Member 1 <member.1@mail.com>,
         Member 2 <member.2@mail.com>,
         ... 
         Member 20 <member.20@mail.com>,
     new.member@mail.com

    so at the moment this looks quit ok, but after check with
    wulf@host ~ $ rt show group/mygroup
    the new member is not added. Same If I try to define by uid.
    e.g. I’m able to edit “privileged” state of a user via cli.

Did I use the syntax correct?
How to define the user (not /user/ID but user to add to members) ?
Is there a known bug? (didn’t find anythink)?

ENV: Debian rt 3.8.8
