Not able to get all custom managed properties from search using Get-PnPSearchConfiguration cmdlets

[ssuryavanshi5]

As, I want to get all refinable managed properties and their mapped crawled properties using pnp powershell module but I could not found any cmdlets for it. SharePoint site has multiple custom properties using Get-PnPSearchConfiguration -Scope Site -OutputFormat ManagedPropertyMappings it returns only 7 custom properties and their mapped crawled properties (not all custom properties) .

Code:

Install-Module PnP.PowerShell -Scope CurrentUser
Import-Module PnP.PowerShell

Prompt the user for the url , clientId and filter property

$url = Read-Host -Prompt "Enter SharePoint URL"
$clientId = Read-Host -Prompt "Enter ClientId"
try {
Connect-PnPOnline -Url $url -Interactive -ClientId $clientId
$ManagedProperties = Get-PnPSearchConfiguration -Scope Site -OutputFormat ManagedPropertyMappings

$output = @()
foreach ($property in $ManagedProperties) {
    $crawledProperties = ""
    foreach ($crawlProperty in $property.Mappings) {
        $crawledProperties += $crawlProperty + ','
    }
    $crawledProperties = $crawledProperties.TrimEnd(',')

    $output += [PSCustomObject]@{
        ManagedProperty = $property.Name
        CrawlProperties = $crawledProperties
    }

}

So, need help like how can i get all refinable managed properties and their mapped crawled properties uisng pnp powershe module.
