How can I import lxc containers back from the snapshots the lxc create just before the `lxc snap` is removed?

I have an Ubuntu 22.04 node, which used to have lxd v5 installed through snap. It used to have 3 containers, at the moment of remove the lxd using the snap remove lxd it did take a snapshot of all the containers , but when I try to import those snapshoted containers I got some errors. First, the snapshots were deliver to me in .zip format, which when I try to import using the lxc import file_name.zip I get the *Importing instance: 100% (108.71MB/s)Error: Unsupported compression* error, weird because as I pointed I got the snapshots in .zip format. So I needed to extract it and then compress it again using tar (tar -czvf containers.tar.gz file_contains_extracteds/) Once I got the correct format, then I try to import it, but I get the following error: lxc import containers.tar.gz Importing instance: 100% (701.66MB/s)Error: Backup is missing at "backup/index.yaml" When I look into the extracted .zip file I get: ls 25112 archive.tgz common meta.json meta.sha3_384 user And inside the common there are all the container's folder: ls common/lxd/storage-pools/default/containers/ monitor orch1 vrouter How can I import lxc containers back from the snapshots the lxc create just before the lxc snap is removed?
