Mac mini 2014 for Xcode??

I am making Electron JS app. on windows it is ready but now i want to test and tweak it on macos. i dont have budget for macbook pro or air. i saw ad of mac mini 2014 and thought i should get it. it is running macos 12 monteray with 8gb ram. what i want:

- electron app signed and notartized by apple, compiling and running on all macos versions
- Optional - IOS app development but i can avoid this for now, macos app is more important.

i dont mind mini being slow or outdated. the main requirement is apps must run on all macos. should i go for it?? other option would be to get 60$/month virtual macos machine but one month is not enough for work.
