Issue Summary

Currently, in the GET Space Permission API there is no way to differentiate a GUEST space permission from a USER space permission

Steps to Reproduce

1. Provide Guest access to an account on a Confluence site
2. Provide read-only access to the Guest for a space
3. Call the /spaces/{id}/permissions REST API 
4. The system will retrieve the space permissions of the guest

Expected Results

The GET API response will provide also information about the fact that the account is a guest

Actual Results

The API will not retrieve information about the fact that the space permission refers to a guest:

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
