Hi everyone,

we are creating an install script for our solution in which we would like to have a step that will create some form of admin user just for that install script with all rights. From client test tool I captured message(right) and what is needed in that message, but unfortunately if I try to recreate same message via client test tool(left), it will throw an exception

Error message would be following:

And if I change what to 82 (AddUser from NotifyType enum), we would get following error:

Also, I tried to create message in this way:

And by using this button, sending message from Client Test tool succeeds. But message type in that scenario is empty so I don't know what to use in the code...

Code is currently looking like this (throwing unknown user group exception):

Did someone encounter similar issue before? Would there be any example in other scripts for this case?

Thanks in advance!
