Flathub App Status in Browser

Hello. I’m new to Flatpak and hub. I have installed some apps by clicking the install link on the Flathub web page, but the status of the app remains at “install” and never changes to remove. How do I get the website to recognize the status of app in my OS? When I click install, a flatpakref file downloads which I click to install the app. I’m using Ubuntu KDE Plasma, chrome and Edge.

The website doesn’t know what your system has installed. Even if that would be possible, there might be people that wouldn’t want this due to privacy.
