I couldn’t find these strings on Crowdin. (Arabic).
סיכום מבוסס בינה מלאכותית
Users reported missing Arabic translations for strings in the DiscoTOC theme component, noting they weren’t found on Crowdin. Moin and Arkshine confirmed the strings are part of the DiscoTOC component’s locale file, and that theme components aren’t automatically added to Crowdin. JammyDodger suggested they can be added manually and looked into it. Later, Lilly confirmed DiscoTOC had been added to Crowdin, thanking users for the report. discojan asked for the component name, which gerhard provided as https://discourse.crowdin.com/discotoc. discojan noted it wasn’t indexed, and gerhard explained the project needed manual publishing — now resolved. The issue is fixed, and strings should now be accessible for translation.

Those strings come from the DiscoTOC - automatic table of contents theme component.
I don’t think theme components are added to Crowdin for translation.
You can easily customize those strings in the settings of the component.

This is located in the Discourse TOC theme component.

I think they can be. We currently only have right sidebar blocks on there https://discourse.crowdin.com/right-sidebar-blocks (though I think table builder was too until it was made a core feature). Let me see how easy it would be to add it.

What is the component name?
It should be visible now. We forgot to publish the project, which is a manual step that can’t be automated via API.
