It looks like what happened is that the upstream project removed that wrapper script. This kind of update probably shouldn't have been submitted for Fedora 32, but now that it's in the wild, I've opened a bug[1] to request the package maintainer add a script that points users to new instructions. You can see the new instructions in the HOWTO.md file in the package repo[2].
