Unassign from groups using IPS

[Rich_S]

I am using the below in my target transformation in IPS to IAS:

{
"condition": "$.userName =~ /^\\d{1,6}$/",
"constant": "PreDay1",
"targetPath": "$.groups[11].value"
},

I want to do the opposite as well, i.e. remove from the group if the regex string is not meant. Can anyone advise how I do that please?

Thanks
