software installation – delete a package/app installed with pacman -U option

I have installed a docker desktop application on my Arch Linux xfce4 and I want to delete it because I want to only use docker-cli (because the docker desktop conflicts with docker-cli in services and daemons).

I installed docker desktop with these steps:

install docker-cli (docker-engine,docker-compose…..all the required stuff)
downloaded the arch package
then did: sudo pacman -U ./docker-desktop-<version>-<arch>.pkg.tar.zst

How can I now remove this package? I have searched the internet but couldn’t find a specific answer.
