Spell check in my language is not available in the flatpak version. On the extension website there’s a beta for spellcheck and hyphenation rules, but that one has last been updated four years ago.
How can I get spell checking for Dutch (my native language) in LO when a recent dictionary is not provided for the flatpak version?
The version of LO which comes with my distribution is very old. The flatpak version is current.
