How to set keybinding to toggle emoji suggestions?

[sierxue]

I'm using ibus-rime on ubuntu 20.04, which was installed by compiling source.

I've installed emoji with plum, and it works smoothly. I greatly appreciate it!

Now I have set the default option as "0", then the emoji suggestions does not show as I expect. I want to set up a shortcut to change the option to "1", and have setup in the schema:

patch:
  'key_binder/bindings': # This does not work as I expect?
     - { when: always, accept: Control+Shift+9, toggle: emoji_suggestion }
     - { when: always, accept: Control+Shift+(, toggle: emoji_suggestion }

However, it does not work, and I cannot see emoji suggestions.
