Custom Toolbar Menu

onCustomToolbarItemTapped returns the identifier of a custom toolbar or custom More-menu item. Built-in toolbar items do not trigger this callback.

<CPDFReaderView
  ref={pdfReaderRef}
  document={samplePDF}
  configuration={configuration}
  onCustomToolbarItemTapped={(identifier) => {
    console.log('Custom toolbar item:', identifier);
  }}
/>

For menu configuration, see Main Toolbar.
