GET Team locked field options

Hello. I am developing Exalate script to synchronize issues from Jira Cloud project to ADO project. I need to sync Team names but I can`t get them from Jira side. If it even possible to get list of Teams names? Or maybe there are some workarounds?
I need request (1) to get names of teams and (2) create team.

I`ve already found ID for Team field in custom field configuration menu: customfield_14601.
Also I can see that this is locked field.

I tried to use such request(from https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-issue-custom-field-options/#api-rest-api-3-field-fieldid-context-contextid-option-get):
GET /rest/api/3/field/{fieldId}/context/{contextId}/option
But I got message that this field does not have options. Although I can see in the issue window that it`s dropdown field.


Also I tried method from here: https://developer.atlassian.com/cloud/jira/platform/rest/v3/api-group-issue-custom-field-options--apps-/#api-group-issue-custom-field-options--apps-
But I got message that Id customfield_14601 or 14601 is not valid.

Also I found unresolved ticket about Advanced Roadmaps API for Jira Cloud ([JSWCLOUD-20360] Implement a REST API for Jira Advanced Roadmaps - Create and track feature requests for Atlassian products.) and Portfolio API but it seems that it is only for Jira server and not cloud. https://docs.atlassian.com/portfolio-for-jiraserver/REST/2.12.0/

There is no way to get Team field right now can you confirm?
