AppleScript app is not recognized as default browser

**Target OS:** Macos 10.15.3 Catalina **Goal:** use apple script bundled to app as a default web browser To debug I'm using very simple apple script, that just show passed url in dialog

on open location theURL
	display dialog "Passed url : " & theURL
end open location

I also added CFBundleURLTypes to Info.plist to claim binding to http\https url schemas

CFBundleURLTypes
	
		
			CFBundleURLName
			My test app url
			CFBundleURLSchemes
			
				http
				https

**The problem:** is that app is not showing up in 'Default web browser' combobox in System Preferences -> General I've tried to dump Launch Service database /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -dump And my app is present there. Also tried force register /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -v -f ./MyTestApp.app Also tried to sign my app by self issued signature. Nothing helped. **What could I miss?** Is there any additional configurations that should be done to let macos recognize my apple scrip app as possible default browser?
