All seems to be working:

changed the description

Thanks for the fixes, though note our CI targets Glade 3.22: you also need to update it to use Glade 3.36.

I encountered another error (soon to be on master): glade_widget_action_get_class() isn't found, what has it be replaced by?

Please mark your commit as fixing #267 (closed) by adding Fixes https://source.puri.sm/Librem5/libhandy/issues/267. at the bottom. :)

Compare with previous version

I fixed a few more issues I mentionned earlier, can you give me write access to the MR so I can push my changes? Otherwise I'll have to make another one but that's not great.
