I found a workaround for global 12keyboard shortcuts, combining a number of tricks I found online.
1. Give each profile a unique name, so they appear differently in the People menu (screenshot https://prnt.sc/qrasm0 )
2. Add an app keyboard shortcut for each profile in System Preferences (screenshot https://prnt.sc/qrasyp ). These only work if you're already focused on a Chrome window, so...
3. Add an Alfred workflow to use a different key combo to launch Chrome and then Dispatch the Key Combos you set in System Preferences (Under Outputs) (screenshot https://prnt.sc/qratzw )
E.g. Option + Shift + 1 triggers the first workflow. The workflow launches Chrome, and then triggers the App keyboard shortcut to switch to the profile called Corey.
