A handy feature of Chrome lets you create Shortcuts for websites.
You can configure it under Chrome > More tools > Create shortcut.
This way the website feels like a Desktop-App since it is separated from the browser window. It integrates well in GNOME (3.38.3). Like normal applications it can be launched from the Activities-View and added to the Dock.
Finally, for me there’s no need for (unofficial) Electron wrappers anymore if I miss a Desktop version of an App.
Credit where credit’s due - I found it through the Web Weekly Newsletter.
