To add to this, I was able to reproduce this on Nobara, a Fedora-based distro.
This issue doesn't seem to be Linux exclusive, a few months ago I was able to reproduce this issue on Windows 11 (I'm not on Windows anymore so I don't know if it is still happening) and I was able to find a work around for the issue.
The post with the workaround can be found here: https://steamcommunity.com/groups/SteamClientBeta/discussions/0/3877093297623891777/
This won't make community layouts appear. I'm guessing that steam sees the DualSense and DualSense Edge controllers as two entirely separate controllers so you need to show all layouts to see the community layouts for normal DualSense Edge controllers
Nothing extracted yet.
Your system information
Please describe your issue in as much detail as possible:
When using the DualSense Edge, there are no template layouts or community configurations.
Affecting both an emulated controller and physical hardware.
