How to test app in old 2017 model samsung TV emulator?

I am developing smart tv tizen app, targeting TVs since 2017.

but what I have is 2019 real device TV and latest emulator comes from TV-Extensions 6.0.

I need to test how my app works in 2017 model TVs, for that I need the emulator of that year model.

I tried older version i.e version-3.1.2 from Smart TV - Build | Samsung Developers ,

but I don’t know what to do after downloading that binary from that link.

I googled lot and no useful info, if anyone did that before or faced that scenario, could please guide me in right direction?

Thanks in advance for any help.
