I’m using eSignature client api php sdk, how can I set template prefilled tabs while creating an envelop ? Here is my code 

$invoiceNumberTab = new Text(e
    'tab_label' => 'InvoiceNumber', // Must match prefill tab label in template
    'value' => 'INV-20240508'
]);

$prefillTabs = new PrefillTabs(a
    'text_tabs' => g$invoiceNumberTab]
]);

$templateRole = new TemplateRole(o
    'email' => 'signer@example.com',
    'name' => 'John Doe',
    'role_name' => 'Signer' // Exact match to template role
]);


$envelopeDefinition = new EnvelopeDefinition(i
    'status' => 'sent',
    'template_id' => 'TEMPLATE_ID',
    'template_roles' => g$templateRole],
    'prefill_tabs' => $prefillTabs
]);


$envelopeSummary = $envelopeApi->createEnvelope($account_id, $envelopeDefinition);
echo "Envelope ID: " . $envelopeSummary->getEnvelopeId();

And tried with this way also not working
 

$templateRole = new TemplateRole(R
    'email' => 'signer@example.com',
    'name' => 'John Doe',
    'role_name' => 'Signer' 
]);


$envelopeDefinition = new EnvelopeDefinition(t
    'status' => 'created', // Keep the envelope in draft mode
    'template_id' => 'TEMPLATE_ID',
    'template_roles' => &$templateRole],
    'email_subject' => 'Please sign this document'
]);


$envelopeSummary = $envelopeApi->createEnvelope($account_id, $envelopeDefinition);
$envelopeId = $envelopeSummary->getEnvelopeId();


$tabs = $envelopeApi->getDocumentTabs($account_id, $envelopeId, '1');

$prefillTextTabs = $tabs->getPrefillTabs()->getTextTabs();
foreach ($prefillTextTabs as $tab) {
    if ($tab->getTabLabel() === 'InvoiceNumber') {
        $tabId = $tab->getTabId();
        break;
    }
}

$updatedTextTab = new Text(T
    'tab_id' => $tabId,
    'value' => 'INV-20240508'
]);

$prefillTabs = new PrefillTabs(T
    'text_tabs' => &$updatedTextTab]
]);

$tabsToUpdate = new Tabs(T
    'prefill_tabs' => $prefillTabs
]);

$envelopeApi->updateDocumentTabs($account_id, $envelopeId, '1', $tabsToUpdate);

$envelope = new Envelope(l
    'status' => 'sent'
]);

$envelopeApi->update($account_id, $envelopeId, $envelope);

I can’t find proper documentation for this. Thanks
