Disable emoji annotation (IBus Preferences)

I have recently found out that the key combination Ctrl + Shift + E in my Xfce Debian 11 does something else than I expected. I use it in Bookstack to change a selected part of text to inline code style like this. Instead of this however, it calls an Emoji annotation (which, frankly, I will never use).

1. To disable this shortcut, open ibus-setup (Applications --> Run program or type ibus-setup in Terminal).

2. This will open IBus Preferences, go to the Emoji tab

3. There, click on the three dots button next to Emoji annotation, select the shortcut and press Delete.

4. The Emoji annotation should now be empty and shouldn't interfere with other application shortcuts.
