Problem:
The client added a minor version of Thai with automatic translation but noticed that the Thai menu differed from the English one, with some items not translated and links remaining untranslated. The client was interested in a fully automated translation solution but was unsure how to find the strings for the menu translation.
Solution:
First, we recommended ensuring that the menu and the pages in the menu are translated into Thai by following the manual translation process:
https://wpml.org/documentation/getting-started-guide/translating-menus/#option-2-translating-menus-manually

Next, we clarified that custom links cannot be automatically translated using the menu sync feature. Instead, we suggested translating them using string translation and then sending the string translation to the automatic translation feature:
https://wpml.org/documentation/getting-started-guide/translating-menus/#translating-custom-links-after-wp-menus-sync
https://wpml.org/documentation/automatic-translation/automatically-translate-strings-with-wpml/#translate-everything-automatically

Lastly, we provided an example of how to search for the menu item strings using String Translation, with a screenshot for guidance:
