tasklist /fo CSV | findstr RDP returns nothing

[322029]

I tried to reproduce what you illustrate here: Remote Execution Guide and find_elements found nothing (remotely from Ansible, using WinRM) #401
Probably, I do not understand remote desktop well, so failed to obtain RDP process ID by $session = tasklist /fo CSV | findstr RDP ; $session = $session.Split(",")[3] ; $session.Split('"')[1]. tasklist did not include the session whose name is RDP.
Below is what I did.

Steps to Reproduce the Problem

1. 'Enable Remote Desktop' in Windows setting, or Enable-PSRemoting in PowerShell
2. psexec -u [user name] -p [password] \\192.168.xx test.bat (test.bat contains python my_script.py)

As for the second step, is it different from psexec -s -i [process ID] test.bat?

Short Example of Code to Demonstrate the Problem

dlg.Edit.click_input(), and dlg.Edit.type_keys() returns error.
The error messages are pywintypes.error: (5, 'SetCursorPos', 'access denied') or RuntimeError: SendInput() inserted only 0 out of 2 keyboard events.

I would really appreciate it if you would tell me the steps to introduce RDP.
