I had a similar issue when I started with Hyprland to set up all the additional programs which usually come with a DE. But there are preconfigured setups which give you a "full DE" experience out of the box and you can customize from there.
I recommend SolDoesTech or My Linux for Work. Both have full guides on Youtube as well for "easy" Arch + Hyprland installs.
Where is this feature officially announced and with which version does it come? Couldn't find anything about this.
