What are the values to be passed in getTagByNameRequest of 'Get Tag By Name' Resource

Hi,

I am trying to get results by calling the API Get Tag By Name by passing a request body (getTagByNameRequest) as explained in [1]. By looking at the documentation I cannot figure out what values I should pass with this payload.

{
  "maxReturn": 5,
  "name": "program",
  "offset": 1,
  "order": "string"
}

Do you think you can help me out here? Below would be the response I get from Get Tag Types

{
:   "success":true,
:   "errors":
:   [
:   ],
:   "requestId":"a66a#1631a8a344f",
:   "result":
:   [
:   :   {
:   :   :   "tagType":"Author",
:   :   :   "applicableProgramTypes":"[email_batch,program,nurture,event,webinar,in_app]",
:   :   :   "required":false
:   :   },
:   :   {
:   :   :   "tagType":"Campaign Topic",
:   :   :   "applicableProgramTypes":"[program,nurture,email_batch,in_app]",
:   :   :   "required":false
:   :   },

And the result I get from Get Tag by Name by passing the name would be

{
:   "success":true,
:   "errors":
:   [
:   ],
:   "requestId":"48df#1631a921f88",
:   "result":
:   [
:   :   {
:   :   :   "tagType":"Campaign Topic",
:   :   :   "applicableProgramTypes":"[program,nurture,email_batch,in_app]",
:   :   :   "required":false,
:   :   :   "allowableValues":"[xxx,yyy,zzzz,dddd,aaaa]"
:   :   }
:   ]
}
