Hide a default Power Apps button in modern UI

Hi,

I tried to Hide flow and Power Apps button from my all Lists using Powershell

Connect-PnPOnline -Url https://jpower4.sharepoint.com/sites/projects
$ctx = Get-PnPContext
$ctx.Site.DisableAppViews = $true;
$ctx.Site.DisableFlows = $true;
$ctx.ExecuteQuery();

It is removed the 'Flow' button and removed the 'Create an app'. But not removed the PowerApps button.

Please help on this.
