A minimote is a now discontinued handheld remote from Aeotec that was useful back in 2015 and 2016 for adding zwave Classic (4th generation) devices to the network when they couldn’t be brought close to the hub since those devices didn’t have Explorer Frames. Old technology for an old problem.
These days the problems and the solutions are different. 
if you did use a minimote on the current generation at the very least you’d be forcing it back to the oldest security level, and you’d also likely screw up associations.
If you happened to have an old model switch and a still functioning minimote you could use it, but it wouldn’t be recommended for a current model switch. 
I continue to ask for the specific model number of the switches involved because, among other things, as @Automated_House noted, if it’s one that supports “SmartStart” with a QR code, that method would definitely be worth trying.
First rule of home automation: “the model number matters.”
