Change the dashboard language
Switch the language you see in the teacher dashboard — separate from the language students see on your site.
The dashboard language belongs to you, not to the school. Open Instructor profile in the sidebar, pick a value in Dashboard language (English, Bahasa Malaysia, 简体中文 or 繁體中文) and save. The dashboard, and the Help Center when you open it from the dashboard, switch to that language. Each teacher on your team can choose their own.
This is not the language students see on your storefront. That one is a school-wide setting under School settings → School profile → Site language, and it only translates fixed interface text (buttons, labels) — never the courses and articles you write yourself.
