Answer
Chromium-based Edge (the current version of Edge since Microsoft rebuilt it on the Chromium engine) is supported alongside Chrome — the guidance to avoid Edge specifically applies to the older, legacy EdgeHTML-based version of Edge (pre-Chromium), which is not supported. If you were told broadly 'don't use Edge' without the legacy-vs-Chromium distinction being made clear, that guidance was likely referring to the older EdgeHTML version rather than the modern Chromium-based Edge most organizations run today.
