Hello,
The PowerShell Accessibility should not be a kind of module to install. You can refer to the document for general accessbilities in PowerShell ISE. https://learn.microsoft.com/en-us/powershell/scripting/windows-powershell/ise/accessibility-in-windows-powershell-ise?view=powershell-7.3
For any detailed accessibilities you need, you can raise up and we can see.
Best Regards,
Ian Xue
