Out-GridView is finally back in PowerShell core - https://devblogs.microsoft.com/powershell/out-gridview-returns/.

The project is hosted on github - https://github.com/powershell/GraphicalTools

Install the module from the gallery -

PS> Install-Module -Name Microsoft.PowerShell.GraphicalTools

Currently, Out-GridView is the only command in the module though adding Show-Command and Show-Object are planned.

The module works cross-platform not just Windows.

You need PowerShell v6.2 or later to build or presumably run the module.
