Jira Service Management API Permissions

My permissions to browse project and edit issues are both set true, when checking through the API.

To use the Jira modules what permissions are required on a project?

I am able to GET jira data using the Make an API Key Auth request with …https://.atlassian.net/rest/servicedeskapi/request/ but the Jira modules fail with permission errors. Using the Search Issue button on a Jira module shows Status code error 403.

I’m attempting to use this with Jira Service Management, where my ID only has access to the customer portal.
