Keyboard changes

Hi
I’m trying to tweak keyboard a bit for this I need to disable the swipe to language change
and use that swipe to something else.
Right now I’ve analyzed the following files in the /usr/share/maliit/plugins/com/jolla dir:

KeyboardLayoutSwitchHint.qml
KeyboardLayout.qml
KeyboardCloseHint.qml
KeyboardBase.qml

from these files I can see only the swipe to close gesture but it seems I’m unable to spot where’s the swipe to change language.
There’s this one file of course:

KeyboardLayoutSwitchHint.qml
but from what I understood it’s only to display language swipe hint but it’s not handling the actual language swipe action.
Maybe someone could drop me some hints where I should look for it or what I’m missing here?
