You can use the API endpoint with method POST (App ID is obscured):

$url = "https://graph.microsoft.com/v1.0/myorganization/applications/057702ab-3ea0-****-***-*******/addPassword"


$appAssignmentHashtable = @{}
$appAssignmentHashtable.mobileAppAssignments = 
@([ordered]@{ "passwordCredential"= 
        [ordered]@{ "displayname"= "TestTN"; 
                    "endDateTime"= "2024-12-30T10:27:35.455Z";
                    "startDateTime"= "2024-07-03T09:27:35.455Z"
};


})

$appAssignmentJSON = $appAssignmentHashtable | ConvertTo-Json -depth 10
$body= $appAssignmentJSON -replace '""','null'

Invoke-MgGraphRequest -Uri $url -Body $body -Method POST -OutputType PSObject

There is also a new Entra Module that can perform this:

New-EntraApplicationPasswordCredential -ObjectId "057702ab-3ea0-******-******"
