Trying to add the Latin American Spanish keyboard layout on IBus for Debian Bulleye in MATE, but I only get Spaniard Spanish

I am running Debian 11 Bullseye for AMD64 on an HP Pavillion Touch 14-N009LA laptop, using IBus and MATE as desktop environment, having upgraded recently from Buster. Prior to upgrading point release, I could use the Latin American keyboard layout with IBus; afterwards, I am no longer able to do so. The Keyboard Preferences app on MATE Control Center shows the Latin American Spanish layout, and I can manually set it with setxkbmap latam on a terminal (before IBus kicks in and replaces it), but on IBus I am only presented with the "Spanish" keyboard, which corresponds to the Spaniard Spanish keyboard that has different punctuation keys; there is no option for "Latin American" or anything similar. Running ibus list-engine gives me the following output, in which I can't see the Latin American Spanish layout, and no matches for latam or anything similar: language: Spanish xkb:es:nodeadkeys:spa - Spanish (no dead keys) xkb:es:sundeadkeys:spa - Spanish (Sun dead keys) xkb:es:winkeys:spa - Spanish (Windows) xkb:es:dvorak:spa - Spanish (Dvorak) xkb:es:deadtilde:spa - Spanish (dead tilde) xkb:es:mac:spa - Spanish (Macintosh) xkb:es::spa - Spanish So far I could only find a guide that only seems to apply to Ubuntu , and the Arch Linux guide for IBus . The former guide suggested that maybe I had to generate a Spanish locale for my system, which I did by uncommenting the es-MX locales from /etc/locale.gen and then running locale-gen. Afterwards, I rebooted my system. It didn't work. Any other idea on how could I use the Latin American Spanish layout on IBus for Debian Bullseye?
