New-EntraApplicationKeyCredential doesn't work "A parameter cannot be foud that matches parameter name 'Value'"

[AndrewShepherd]

I am attempting to execute New-EntraApplicationKeyCredential, following the documentation as written.

To Reproduce

I am attempting to upload a certificate, strictly following the steps in the documentation.

Executing this command:

New-EntraApplicationKeyCredential `
    -ApplicationId $app.Id `
    -CustomKeyIdentifier $base64Thumbprint `
    -Type 'AsymmetricX509Cert' `
    -Usage 'Verify' `
    -Value $base64Value `
    -StartDate $cert.GetEffectiveDateString() `
    -EndDate $cert.GetExpirationDateString()

Results in the following error:

Add-MgApplicationKey: A parameter cannot be found that matches parameter name 'Value'.

Expected behavior

Since I followed the documentation, I expected my certificate's public key to be uploaded to Entra and associated with the Entra application.

Additional context

[CATgwalker]

"Usage" is also not a valid parameter. It appears that the New-EntraApplicationKeyCredential wrapper is not building the Params hashtable to correctly call Add-MgApplicationKey.
