Uploading app icons for manage apps in intune using microsoft graph SDK Powershell

I'm working on something similar, used this blog post https://rozemuller.com/add-microsoft-store-app-with-icon-into-intune-automated/ for that. Basically you create a Base64 of it

$imageUrl = "https://apps.microsoft.com/store/api/ProductsDetails/GetProductDetailsById/{0}?hl=en-US&gl=US" -f $exactApp.PackageIdentifier
$image = Invoke-RestMethod -Uri $imageUrl -Method GET
$wc = New-Object System.Net.WebClient
$wc.DownloadFile($image.IconUrl, "./temp.jpg")
$base64string = [Convert]::ToBase64String([IO.File]::ReadAllBytes('./temp.jpg'))

and use that as icon like this, type should be string:

$deployUrl = "https://graph.microsoft.com/beta/deviceAppManagement/mobileApps"
$appBody = @{
    '@odata.type'         = "#microsoft.graph.winGetApp"
    description           = $appInfo.ShortDescription
    developer             = $appInfo.Publisher
    displayName           = $appInfo.packageName
    informationUrl        = $appInfo.PublisherSupportUrl
    largeIcon             = @{
        "@odata.type"= "#microsoft.graph.mimeContent"
        type = "String"
        value = $base64string 
    }
    installExperience     = @{
        runAsAccount = $appInstaller.scope
    }
    isFeatured            = $false
    packageIdentifier     = $appId
    privacyInformationUrl = $appInfo.PrivacyUrl
    publisher             = $appInfo.publisher
    repositoryType        = "microsoftStore"
    roleScopeTagIds       = @()
} | ConvertTo-Json 
$appDeploy = Invoke-RestMethod -uri $deployUrl -Method POST -Headers $authHeader -Body $appBody
