Hi maintainers,

I realize I do not know how to download debug symbols for flatpak applications. How do I access them to help coredumpctl provide useful debuggine information?

flatpak info im.riot.Riot

Element - Create, share, communicate, chat and call securely, and bridge to
other apps

I don't think we have proper debug symbols for Element since we just repackage the upstream release which doesn't provide them.
