/context/mapping REST endpoint does not work on Team Managed Project

Endpoint POST /rest/api/3/field/{fieldID}/context/mapping is not supported by a Team Managed Project, it will only work with Company Managed Project

Steps to reproduce the behaviour on a TMP project:

1. Prepare Jira Cloud instance with developer canary program (install "developer assistant for Jira" from marketplace)
2. Create custom field type: single select which options
3. Create a team-managed project with an issue that has assigned a select custom field to the screen
4. set some option in this custom field
5. create request POST /rest/api/3/field/{fieldID]}/context/mapping (The Jira Cloud platform REST API) auth method - JWT token

RESULT

request returns the error message "These projects were not found: {projectID}"

This request is to have the endpoint behaving equally on both Company and Team managed projects.
