You totally can friend (I would need to test on which version, the one I used to export the package is the 2021.1 one and as far as I can tell, I didn't use any strictly 2021 feature, so should work on most prev versions too from 2020 or even 19)
Make sure to obviously try the unitypackage option friend! And feel free to tell me about your experience using it later on (be that a good or bad one, everything helps).
