Doesn't work on non-US keyboard layout

[bottine]

On fedora 38 with a non US layout (bépo), this doesn't seem to work. I can choose the input method, but it doesn't do anything.
For it to work, I need to toggle the "US keyboard layout" option on the screenshotted setting menu, which makes it pretty useless.

I'm pretty sure this is an upstream issue, but thought of sharing it here in case someone knows a workaround and/or to let people know. Feel free to close the issue in case you don't want it here, and thanks for the work :)

Edit It's actually stranger than not working: the slash key seems to activate some substitution mode, but with no actual effect.
