OpenSSH does not have the same rights as RDP; although I am authenticated. AU vs IU?

Terminal issue? please go through wiki

Please answer the following

"OpenSSH for Windows" version
((Get-Item (Get-Command sshd).Source).VersionInfo.FileVersion)
8.1.0.0

Server OperatingSystem
((Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows nt\CurrentVersion\" -Name ProductName).ProductName)
Windows Server 2019 Standard

Client OperatingSystem
Linux, macOS

What is failing
get-service

Expected output
List of services

Actual output
get-service : Cannot open Service Control Manager on computer '.'. This operation might require other privileges.

get-service works normal when I log in with RDP. However, I do not want to use RDP.

If I modify the SDDL with sc.exe sdset so that the record for AU is
(A;;CCLCRPRC;;;AU) then the get-service returns.
Obvious using RDP the user becomes an Interactive user instead of only an authenticated user.
I think that beats the purpose of SSH.
Since I am authenticated properly, security cannot be an issue.

Similar issues occur with ssh-add. the agent refuses to handle my requests.

Start with the linked Troubleshooting Steps and TTY/PTY support wiki pages, then reproduce get-service and ssh-add over OpenSSH while comparing the SDDL behavior for AU and IU with an RDP session. A useful resolution would establish whether the differing permissions are intended and clearly state the required behavior or configuration.
