Yes. Also, see:

Using a Non-Safari, Non-Chrome Browser

Thank you so much, @peternlewis. JavaScript works after running these commands in the Terminal: defaults write com.stairways.keyboardmaestro.engine AppleScriptGoogleChromeBundleID -string "com.microsoft.edgemac" defaults write com.stairways.keyboardmaestro.engine BrowserGoogleChromeName -string "Microsoft Edge" It looks promising.

for making it work now by making Edge the Chrome browser.
