[Other] Typing "opt-`" to get a grave accent on the next letter (e.g. 'è') in any app opens Chatbox instead of typing the character

Could this shortcut be removed from Chatbox? I always have to close Chatbox before I can type letters like à, è, and ò, in any app on macOS, because it will switch to Chatbox instead of typing this character.
