How to perform for virtual app testing on old phones such as Infinix X507, Techno Y2 & Nokia 2.1?

Hello nerds!

Here's a problem....

I want to test my android app on Infinix X507 (android 4.4.2 kitkat), Techno Y2 & Nokia 2.1 phones.
I have gone through a lot of online tools like BrowserStack, SauceLabs, BitBar etc but none of them had above devices in their device list.

Kindly help me. Suggest me some relevant tool or an alternative so that I can get my app tested on above devices.

Thanks much!
