Work this article? Translate Footer Library

Hello, I need translate Footer.

Ths footer is in Theme Panel Library. I have translate it but I dont find this step

This step is the most important, first, install the WPML String Translation plugin, then, get your translated template ID (first screenshot below), go to WPML > String Translation, select admin_texts_theme_mods_oceanwp in the Select strings within domain: field, click on the translations link of the custom parts you want to translate so if it is your custom header, it is the [theme_mods_oceanwp]ocean_header_template name, to finish, add your translated template ID in the textarea, check Translation is complete and click Save.

Where do I search admin_texts_theme_mods_oceanwp?? I dont find this string or context.

Thank you
