How to add descriptions to custom project settings?

I create some custom project setting for my addon when the plugin starts up. Something like this:

ProjectSettings.set_setting("addons/portals/gizmo_exit_outline_active", true)

I’d like to add descriptions to such settings. So that when I hover them in the settings window, it shows the BB-code formatted docstring.

I know about the ProjectSettings.add_property_info, it works as expected, but doesn’t allow me to specify any documentation.

Thanks for any tips.
