Non-Administrator domain account cannot remote managing Hyper-V 2016 core

hyper-v

I have a Hyper-V 2016 core server installed. We can authenticate using the Hyper-V Manager with the network domain account. We want to use the 'BUILTIN\Hyper-V Administrator' group to delegate access.
Currently, using GPO we have a test user assigned via Restricted Groups to 'BUILTIN\Hyper-V Administrator' and 'BUILTIN\Remote Desktop Users'
The test account can access local Hyper-V instances but cannot access the remote hyper-v server through Hyper-V Manager on a local client.
The account is able to RDP to it and obtain the CMD/Powershell terminals. We also confirmed that the account shows up in 'net localgroup Hyper-V Administrators'
What other settings need to be configured to assign this role?

Update1-2018-08-17
Here is the current localgroup and domain group settings from the Hyper-V Administrators groups
Group settings
I am able to remotely login with the Hyper-V Manager using the Domain Administrator successfully, but when using the 'stefan' domain account it fails with the following
Error message
The powershell cmd 'Enable-PSRemoting -Force' was run and the server was rebooted already.
The users in the 'Hyper-V Administrators' account are able to run Hyper-V Manager on their local machines without an issue.

Best Answer

I was able to get this to work.
The Domain User needs to be added to the following local groups.

Which can be done via GPO 'Restricted Groups'

BUILTIN\Hyper-V Administrators
BUILTIN\Remote Management Users
BUILTIN\Remote Desktop Users

Do a gpupdate /force on the Hyper-V server afterwards
