SteamLink Install Error

Getting an error when trying to install SteamLink on raspberry pi 4 (Debian GNU/Linux 11 (bullseye) 64-bit).

I have already run the commands to install flatpak, and added the flathub repository

flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

flatpak install flathub com/valvesoftware.SteamLink**

Edit:

flatpak install flathub com.valvesoftware.SteamLink

I rebooted and I still get the error

Nothing matches com/valvesoftware.Steamlink in remote flathub

I saw this user had the same error, but no resolution:
