Add space to chord name

The handbook says that the command to add a space to a chord name, for the Mac, is Command Space. However, this command is used by macOS to open the system-wide Spotlight Search, and this takes priority over the app. I looked at the Shortcuts list in Preferences to see if I could substitute my own shortcut, but this particular function does not seem to be listed among the Shortcuts. Any way I can get around this? If not, then this is a request to make this a configurable shortcut.
