Hi @Miehau, thanks for taking the time to put this PR together, we really appreciate it!

In addition to the title change you made, I think it'd also be a good idea to update the button text as well. This actually manifests itself in a number of places:

1. Button text:
   

   kibana/x-pack/plugins/security/public/management/roles/edit_role/privileges/kibana/space_aware_privilege_section/space_aware_privilege_section.tsx

   Lines 199 to 202 in bf04235

   	<FormattedMessage
   	id="xpack.security.management.editRole.spacePrivilegeSection.addSpacePrivilegeButton"
   	defaultMessage="Add space privilege"
   	/>

2. Corresponding test title:
   

   kibana/x-pack/plugins/security/public/management/roles/edit_role/privileges/kibana/space_aware_privilege_section/space_aware_privilege_section.test.tsx

   Line 87 in b82cc6e

   it('Renders flyout after clicking "Add space privilege" button', () => {

3. A number of documentation references in this file should be renamed to reflect the updated button text (a quick find of "Add space privilege" in this file will assist):
   

   kibana/docs/user/security/authorization/index.asciidoc

   Line 20 in 896b9cd

   To assign {kib} privileges to the role, click **Add space privilege** in the Kibana section.

4. One additional doc reference:
   

   kibana/docs/user/security/reporting.asciidoc

   Line 45 in 7aa600b

   . Add space privileges.

Ah, my bad! Should have used better grep expression searching for that! I'll try updating that tomorrow!
