Change keyboard shortcut for autocomplete on Mac OS

I just found out that Mac OS has a builtin autocomplete functionality that works in many places, triggered by the keyboard shortcut option-esc. However, this shortcut is very bad - I'd like to be able to change it to something else.

I'm having no luck finding this in the Keyboard settings. Is there a way to change this shortcut?

Thanks!

There is a way to change the keyboard shortcut:

1. Go to System Preferences > Keyboard > Shortcuts
2. Click 'App Shortcuts' and press the '+' button
3. A new sheet appears. Select 'All Applications' and enter "Complete" as the Menu Title.
4. Click in the white area next to 'Keyboard Shortcut:' and press your desired keyboard shortcut.
5. Click 'Add' to confirm.

⌘+shift+A is the default shortcut and works fine on Mac OS Mojave.
