Jalankan skrip:

  1. Muat ulang halaman di presentasi Slide.
  2. Klik Ekstensi &gt; Menerjemahkan Slide &gt; Mulai. Mungkin perlu waktu beberapa detik untuk menampilkan item menu add-on.
  3. Saat diminta, izinkan add-on.
  4. Sekali lagi, klik Ekstensi &gt; Menerjemahkan Slide &gt; Mulai.
  5. Tambahkan teks ke presentasi Anda dan pilih teks tersebut.
  6. Di add-on, klik Terjemahkan untuk mengganti teks yang dipilih.
