Is there a way to reload the .XCompose file in Fedora?

I am currently custumizing my .XCompose file in Fedora 29 Workstation (with the default GNOME 3, Wayland, etc). It seems that it does follow the rules I add to the ~/.XCompose file, but if I make changes to it then they are only noticed after I log out and log back in again. Is there something I can do to make the changes take effect immediately? I tried running ibus restart on the terminal but it didn't seem to work. Actually, doing that broke the compose-key functionality completely and I had to restart the session again to fix it.
