What's the equivalent -Function to diw in vi mode

[sharpchen (sharpchen)]

I've tried to set a keymap to perform the same as diw. I thought it should be -Function DeleteWord but this does not behave the same.

Set-PSReadLineKeyHandler-Chord ' , '-Function DeleteWord -ViMode Command

Set-PSReadLineKeyHandler-Chord ' , '-ViMode Command -ScriptBlock {
[Microsoft.PowerShell.PSConsoleReadLine]::ForwardChar()
[Microsoft.PowerShell.PSConsoleReadLine]::BackwardWord()
[Microsoft.PowerShell.PSConsoleReadLine]::DeleteWord()
}
