// Perform a search to locate text signatures in the document
const options = new signatureLib.TextSearchOptions();
const signatures = signature.search(signatureLib.TextSignature.class, options).toArray();
if (signatures.length > 0) {
// Edit the text of the first identified signature
const textSignature = signatures[0];
textSignature.setText('New Text');
const result = signature.update('output.pdf', textSignature);
// Verify the changes made to the signature
if (result) {
console.log(`\nSignature was updated successfully`);
}
