How to translate strings in Gutenberg editor

I use Loco Translate to customize or add missing translations of strings that come from your plugin. I noticed that strings, which appear in the Gutenberg editor (e.g. “Hide Modified Info on Frontend” in the meta box “Modified info”), are not translated, although they are listed in the POT file. Browsing the code of your plugin reveals that the strings in question come from a Javascript file:
wp-content/plugins/wp-last-modified-info/assets/block-editor/build/index.js

Maybe this helps to work out a solution:?https://localise.biz/wordpress/plugin/manual/json
