XLSX file won't open: a blank word processor opens instead

My computer runs a Debian 12-based system with LXDE and all updates installed.
When I try to open an XLSX file, a blank word processor or document editor opens instead. I haven’t found a way to open XLSX files correctly.
I can open them if I first open the spreadsheet editor and then open the XLSX from there, but I don’t want to have to do that every time I want to view a document.
What can I do? Let me know if you need any additional information.

Hello @alejo89

What is the version of Desktop Editor you are using and its installation type, e.g. DEB package, flatpak, etc?
