Currently, it is not possible to search space property keys in an entire site via API

Current behavior

The available APIs needs a space (space id)  to be defined in the API endpoint:

• Get space properties in space API

This prevents a user/script to search a space property key within an entire site given that a space id is currently mandatory on the endpoint /spaces/{space-id}/properties

While, on the corresponding Jira API /rest/api/3/search , it is possible to add a query parameter "properties". No project id is required on the API endpoint.

This allows the Jira API to retrieve project properties keys within the site without necessarily defining a project id.

Expected behavior

Have an additional query parameter "properties"  on the  /wiki/rest/api/search that allows searching for space properties within an entire site
