But the colleagues from have provided the download addresses here. I haven't found a download address at Microsoft in the Update Catalog or a KB article yet.

For Windows 8.1, which is still in support, the update KB4567409 should also be available via Windows Update. But it doesn't offer updates automatically (doesn't work)-I have to download and install them manually. I have not seen the update on my Windows 7 SP1 system with an ESU license. However, Windows 7 SP1 requires an ESU license, as the prerequisites explain. The update comes via Windows Update, as you can read in the KB article. So it is the new Chromium Edge browser for Windows 7 SP1 and Windows 8.1 and the corresponding server versions. Additionally, this new version provides great support for the latest rendering capabilities, modern web applications, and powerful developer tools across all supported OS platforms. This new version provides best in class compatibility with extensions and websites.

Microsoft has released a new Chromium-based version of Microsoft Edge. In the support article of 17 June 2020 it says Microsoft provide update KB4567409 for Windows 7 and Windows 8.1. Now Microsoft is taking the next step, as the colleagues reported here. I had the details in the blog post Windows 10: Chromium Edge are rolled out to user. At the beginning of June 2020, Microsoft started to deliver the new Chromium Edge browser for various Windows 10 versions. The new Chromium Edge Browser is available as a download since mid-January 2020 for various Windows versions and other operating systems (see Microsoft Chromium-Edge released).
