I have a grid display with a Status button. I want to pass a CertificateID ($_.CertificateID in the code below) to a form that pops up in a modal window. I have a $CertificateID parameter defined in the New-UDInput endpoint to receive the variable. Haven’t been able to figure out how pass it from the grid to the modal form.
New-UDPage -Name "Certificate List" -Icon list -Content {
    $CertificateListColumns = @('CertificateID', 'Subject', 'Thumbprint', 'NotBefore', 'NotAfter')
    $CertificateListHeaders = @('CertificateID', 'Subject', 'Thumbprint', 'Start Date', 'Expire Date')
    New-UDColumn -Size 12 {
        $newUDGridSplat = @{
            FontColor       = 'White'
            Title           = "Certificate List"
            Headers         = $CertificateListHeaders
            PageSize        = 20
            Properties      = $CertificateListColumns
            BackgroundColor = 'Black'
            Endpoint        = {
                $Data | ForEach-Object {
                    [PSCustomObject]@{
                        CertificateID     = $_.CertificateID
                        Subject           = $_.Subject
                        Thumbprint        = $_.Thumbprint
                        NotBefore         = New-UDElement -Tag 'div' -Content { Get-Date($_.NotBefore) -f 'yyyy/MM/dd HH:mm' }
                        NotAfter          = New-UDElement -Tag 'div' -Content { Get-Date($_.NotAfter) -f 'yyyy/MM/dd HH:mm' }
                        Status            = New-UDButton -Text "+" -OnClick {
                            Show-UDModal -Content {
                                New-UDRow {
                                    New-UDColumn -Size 6 {
                                        New-UDInput -Title "Certificate - Status Update" -BackgroundColor black -FontColor cyan  -Id "CertFileEntryForm" -Content {
                                            New-UDInputField -Type 'select' -Name 'Status' -Placeholder 'Status'  -Values @("--Select One--", "Requires Review", "Renewed")
                                            New-UDInputField -Type 'textarea' -Name 'Notes' -Placeholder 'Notes'
                                        } -Endpoint {
                                            param(
                                                $CertificateID,

                                            )
                                            New-UDInputAction -Content (
