Ability to get Space Permissions via REST API

Problem

For maintenance purposes we are trying to list all space permissions in Confluence. The following path is used for this: "/rest/api/space/{Space-Key}?expand=permissions" but unfortunately, the REST API does not provide a result here.

Suggested Solution

Please extend the REST API so that space permissions can be read. Similar to solution that already exists with Confluence Cloud.

Why this is important

This is essential to control user permissions around Confluence.
