Are you trying to do this in the Windows Terminal or a vintage console window (conhost.exe, i.e. what you get from running pwsh.exe directly)?

I'm using windows terminal with default profile of pwsh.exe

I'm not much of a PowerShell user, so forgive my ignorance, but is the intent of the ScrollDisplay functions to pan the viewport over the scrollback buffer? Because if that's the case, I wouldn't expect it to work. The key combinations are probably getting through fine, but PowerShell would have no way of controlling the viewport position in Windows Terminal. This is essentially the same problem as issues #9622 and #10191.

I am pretty sure that's how that works.

You may be interested in the various different scrolling actions in the Terminal, which are bound by default to:

terminal/src/cascadia/TerminalSettingsModel/defaults.json

Lines 383 to 390 in 0a7310d

	// Scrollback
	{ "command": "scrollDown", "keys": "ctrl+shift+down" },
	{ "command": "scrollDownPage", "keys": "ctrl+shift+pgdn" },
	{ "command": "scrollUp", "keys": "ctrl+shift+up" },
	{ "command": "scrollUpPage", "keys": "ctrl+shift+pgup" },
