How to add a multi-language configuration file to the menu items I added

The previous menu item is theia’s own, and the latter is added by me, but when I switch the language, only the previous one changes.
I looked at the source code of the plug-in and saw that the language switch is defined in json. I would like to ask how can I add my own configuration to json

Hi @ayuantao, thank you for your question.

I wrote a short explanation on how to use the localization feature of Theia in this thread. If you have any questions on that, feel free to ask them here.

Also, you remind me, that I’ll have to write some documentation on localization for the Theia website.

Additionally, I just published the PR for the documentation on i18n on the Theia website.
