Signal Desktop on Arch Linux

As I mentioned earlier I am using Manjaro Linux on my old laptop, and the repo of the distro it based on, Arch Linux, actually has Signal Desktop. However, it is not up-to-date, which is understandable because it is not "officially" released by Signal. Well, there is always the option to compile from source. I saw the package.json and I know it gotta be using npm. Did a npm install but apparently I also need to install yarn first. Then I just followed the steps in this post:

npm install yarn
yarn install
yarn generate
./release/linux-unpacked/signal-desktop
