They are dependencies of this patch, that needs to be pushed before this patch.

It is to change and amend the behaviour. It adds missing features and fixes
icons+privilege-management+disk-management.

I apologize. I spent whole day to create these patches and throughly testing
them. If I missed anything, please understand it would not have been
intentional. Also, there is a v2 patch in #40753 thread that has 3 blockers.

Thank you for considering my request.
