Long time ago I used Amethyst, so I can’t tell precisely. But this asi answer by LLM-

1. Open Amethyst.

2. Tap your profile icon (top-right).

3. Go to “Settings”.

4. Scroll down to the “Translation” section.

5. Enable translations.

6. Below that, select a Translation API provider — usually LibreTranslate or Google Translate.

7. If needed, enter the API URL (some providers like LibreTranslate are free and don’t need an API key).

Once it’s set up, you’ll see a “Translate” button under posts in other languages.
