Rename the form fields

[Arun-kumar002]

// I'm trying to rename form fields using field.acroField.setPartialName
fields.forEach(field => {
const originalName = field.getName();
const newFieldName = page_${pageNumber}_${originalName};
field.acroField.setPartialName(newFieldName);
});

// After the update, I am not able to read the form fields' values
const fields = form.getFields();
console.log(fields); // []

The scenario is: I have a table in my PDF. After clicking on "New Page," I need to add a duplicate of the page below the current one.
