Funny, I do similar [1] though my solution is very basic compared to yours. The script allows me to quickly move the current tab from Firefox or Safari to Arc Browser [2] (which uses Chrome under the hood).

I use the following key-bindings ⌥⌘F or ⌥⌘S in Raycast [3] to activate a tab move to Arc from Firefox or Safari, respectively.
