What RackTime (or any others) quick release system does this work with?

I got a new bike and it came with this rear rack from RackTime. I’m having a lot of trouble figuring out which model rack it is and if it’s compatible with the RackTime SnapIt 1.0 or 2.0 (or neither? Or any other kind?). The manufacturer website says 1.0 but it also says it’s not a RackTime rack (It says it’s a Tubus rack). Additionally, all the parts of it are metal— no plastic brackets or moving pieces

Im looking to get a basket i can attach to it but be able to unsnap and remove it easily. Any help is appreciated!
