Installing offline help for current flatpak installation

[Bemused]

Trying the flatpak install in Linux Mint but can’t find any way to download and install the offline help. The deb file for the same edition fails to find dependencies, so can’t be easily installed.

Revised… I appreciate the comments given. However, I have decided to switch back to a DEB installer to use the ‘Fresh’ branch of Libreoffice and to more easily add the offline Help files, so I won’t be checking in here.

Same here. I installed the flatpak version in Lubuntu, and i don’t know how to install the offline help.

Found a package. When to search then you don’t find all packages. When to start installing and using CLI autocomplete then you see all packages:

$ flatpak install flathub org.libreoffice.LibreOffice #quickly 2xTAB
org.libreoffice.LibreOffice          org.libreoffice.LibreOffice.Help     org.libreoffice.LibreOffice.Sources
org.libreoffice.LibreOffice.Debug    org.libreoffice.LibreOffice.Locale

Is this still valid? The flatpak appeared to download and install correctly, but LibreOffice cannot successfully launch the help. LibreOffice points a web browser to this path:

file:///var/lib/flatpak/runtime/org.libreoffice.LibreOffice.Help/x86_64/stable/c269e6432bbc3a22b6666ca13380ead34e55e8681411edf53417fc2d37cdc9d3/files/index.html?Target=sdraw/.uno%3AHelpIndex&Language=en-US&System=UNIX&Version=7.3

but the browser throws this error:

File not found

Firefox can’t find the file at /var/lib/flatpak/runtime/org.libreoffice.LibreOffice.Help/x86_64/stable/c269e6432bbc3a22b6666ca13380ead34e55e8681411edf53417fc2d37cdc9d3/files/index.html?Target=sdraw/.uno:HelpIndex&Language=en-US&System=UNIX&Version=7.3.
