# This script will search all open Browser Windows for a specified Tab (by Title).  
# At some point, this worked for Google Chrome and Brave Browser.                  
# Other chromium based browsers should work, but have not been tested.
#																       
# If no tab with the given title is found, it will open the specified URL in the		
# specified Profile.	 If multiple tabs with the specified title exist, the first one 	
# found will be opened.	
# 
# Chromium's applescript APIs does not offer support for changing the browser profile, so we need to emulate clicks on the relevant elements.
# Due to this, the application that is going to run the script (a hotkey application (BetterTouchTool, KeyboardMaestro), or e.g   	
# Terminal) will have to be granted Accessibility Access (System Preferences > Security & Privacy > Privacy > Accessibility)
# 																	
# 																	
# Params:															
#		browser: the name of the app ("Google Chrome", "Brave Browser", ...)	
#		profileName: the exact name of the profile to be matched			
#		targetTabTitle:  exact or partial tab title, as specified in the <title> tag		
#		targetUrl:	   the url to open, including http(s)://					
# 																	
# osascript ~/path/to/scriptname.scpt "Brave Browser" "My Profile Name" "Exact or partial <title> of the tab" "https://URLToOpenIfTabtIsNotFound.tld"

If you're not using Brave, you'll probably have to replace all instances of "Brave Browser" in the script with your flavour of chromium (e.g. "Google Chrome",..)
