Why is there no LibreOffice in the Gnome Software that I can install from the repos?

Might be a noob question, but I dont understand this. I'm running Tumbleweed with Gnome. When I search for LibreOffice (the whole suite, not a single program) in the Software app, I can only install it as flatpack. Still I can install it via zypper install libreoffice which installs it from the repos, I guess. Why doesn't Software find LibreOffice in the repos?
