Make Secondary Title WPML Compatible

It would be great if the plugin Secondary Title could be WPML compatible. Meaning that the titles can be translated with WPML. Right now they have to be manually edited one by one, which is very time consuming. I asked ChatGPT for suggestions, and this is what it said to me:

To make your “secondary title” WordPress plugin WPML compatible, you will need to follow these steps:

1. Make sure that your plugin is ready for localization by using the appropriate functions such as __() or _e() to wrap all translatable strings in your plugin code.
2. Create a new folder in your plugin’s root directory called “languages”. In this folder, you will need to create a .pot file which is used to extract all the translatable strings from your plugin.
3. Use a tool like Poedit to open your .pot file and create .po files for each language that you want to support. These files will contain the translations for your translatable strings in each language.
4. Once you have your .po files for each language, you can then compile them into .mo files using a tool like Poedit.
5. In your plugin code, you will need to load the appropriate .mo file for the user’s language. To do this, you can use the load_plugin_textdomain() function, passing in the name of your plugin, the path to your languages folder, and the domain of your plugin.
6. Finally, you will need to make sure that your plugin is compatible with WPML’s translation management system. This involves using the appropriate WPML functions to register your plugin’s strings for translation and to retrieve the translations when needed.
