Before macOS Sonoma Dock web apps existed, I was an avid user of Fluid (https://www.fluidapp.com). I placed my Gmail in a standalone web app, and links in the web app I could right click and select “Open in default browser” which caused the link not to open in the web app but in the default browser (e.g. Safari).
How can I replicate the same behaviour with macOS Dock’ed web apps? I like to have my Gmail in a web app, but be able to open a link in an email in plain Safari.
