"Permission denied" while finishing Installation as user

Hello,

I wanted to switch from native Libreoffice to the Flatpak, in order to increase security, however, when trying to install this package as my unprivileged user I get the following Error:

Error: Permission denied
error: Failed to install org.libreoffice.LibreOffice: Permission denied

Installation using sudo works, but I would prefer it to be installed in my user context and be manageable by flatseal there.

OS: openSUSE Tumbleweed 20221210 uname: Linux yla 6.0.10-1-default #1 SMP PREEMPT_DYNAMIC Sat Nov 26 17:59:17 UTC 2022 (582305b) x86_64 x86_64 x86_64 GNU/Linux Flatpak version: 1.14.1

I have set my OS permissions to fairly paranoid, so this might be an issue with DBus access?
