I'm looking for a way to use Azure API Management (either the management portal or an API call) to edit the textual description of the Ocp-Apim-Subscription-Key Request header fields. This string shows up in auto-generated documentation, but I can't figure out where it's set. So far I've tried looking for the description string for the Ocp-Apim-Subscription-Key in the swagger file and in the API Management Publisher Portal, but haven't been able to find it.
Here is a screenshot highlighting the field in the generated API documentation that I want to edit:
Here is the page in the Azure API Management Publisher Portal where I looked for a Request Headers section and couldn't find it:
Other answers to questions about Azure API Management make me wonder if there's a REST API call to edit this string (if it's not available in the Publisher Portal) but I can't seem to find an active link to API documentation about it.
