Is Tata PLAY available on any device?

[shankarcams]

Hi. I use the Tata Sky app "Tata Play" on my phone. However it is not available on Fire TV Stick unless some sideloading is possible.

Can anyone advise
a) How to load Tata Play app on Fire TV
OR
b) Any other video streamer where we can install Tata Play

Thanks a lot!
