How to get possible options for a custom "label" field via the REST API (v2 or v3)?

[Julian Götze]

Setup:

I created a custom field with "Labels" via the Jira UI:

Motivation:

I want to access all available options for this label from within a forge app, using the Rest API v2/ v3 (to create a custom issue-creation dialog in our application). 

Problem:

- First, I call

/rest/api/3/issue/createmeta/${projectIdOrKey}/issuetypes/${issueTypeId}

to obtain the create-issue metadata (containing the customField)

- In the response, the custom field yields the

 autoCompleteUrl:"https://api.atlassian.com/ex/jira/.../rest/api/1.0/labels/suggest?"

- But when trying to call this endpoint from my forge-app, I always get a

{ code: 401, message: 'Unauthorized; scope does not match' }

Question (or what I've tried so far):

Is there a v2/v3 equivalent for "https://api.atlassian.com/ex/jira/.../rest/api/1.0/labels/suggest"?

I've tried:

- `/rest/api/3/label` -> only yields the system-labels

- `/rest/api/3/field/{fieldId}/context/{contextId}/option` -> yields:  errorMessages: [ "The custom field doesn't support options." ])
