telnet not working

Question

I run Windows Server 2019. I want to use and test telnet between server 2019 and workstation 10.
I installed telnet on the server.
I installed telnet on the workstation.
I enabled in both server and workstation port 23 (I created inbound and outbund rules allowing TCP port 23).
I start telnet from CMD?
Microsoft Telnet> o localhost 23
Connecting To localhost...Could not open connection to the host, on port 23: Connect failed
I don't see the telnet service running in "services" on both workstation and server.

When i run this powershell command, i get this message:
PS C:\Windows\system32> Test-NetConnection -Computer localhost -Port 23
WARNING: TCP connect to (::1 : 23) failed
WARNING: TCP connect to (127.0.0.1 : 23) failed
ComputerName : localhost
RemoteAddress : ::1
RemotePort : 23
InterfaceAlias : Loopback Pseudo-Interface 1
SourceAddress : ::1
PingSucceeded : True
PingReplyDetails (RTT) : 0 ms
TcpTestSucceeded : False

Can someone help me please?
Kind regards

According to this site, Microsoft has removed the Telnet Server feature and you would need to use a 3rd party tool.

Why do you want to use Telnet? OpenSSH is a more secure and both the client and server can be installed as a feature.

Or you could use Powershell.
