The new widgets should be available for normal use (without the hassle of the above instructions) in the next nightly that @gmc will probably push out tomorrow 
EDIT: please, see this nightly release: 17.8-432
It now includes the additional widgets under Settings/Interface/Skin/-Customize skin/Customize Home Menu. There you’ll find the Skin Helper Service Widgets under Manage widgets/Select widget/Standard widgets. If a PVR addon is active, you’ll find a PVR section there as well with one if them being the one you requested, @gb160 
I’ll mark this as solved for others to easily find the solution for your request 
If there’s anything missing, feel free to ask.
