Email client templates visibility for specific group

[Ciobanski]

Hello,

I am working on some Email Client Templates for Service Operations Workspace, and I got them figured out, now I am trying to create a condition so that the templates are visible for selection in the compose section only if the user who is on the record at the moment, is part of a certain group. 

The script itself is created, however I cannot find anywhere how to call it in a template.
Tried with the filters, but not sure which field (on incident or catalog task) should I use.

Is this feasible in ServiceNow? I have searched everywhere and I do not see any condition for this. Of course, without the implementation of custom fields. 
In case it is feasible, if it can be done without scripting, I am more than thankful for such a solution.


Thank you in advance!

Kind regards,
Daniel C.
