I updated the metadata.json and debian/control for this extension locally and tried to use the extension. But I got errors and I don't have the time now to investigate further. This extension will likely be removed from Testing when we start the GNOME Shell 48 transition within a few days. April 15 is the deadline for the package to make it back into Testing to be included in Debian 13.
