Hi there,
I am not naturally a whizz with Amazon Fire Tablet, as I have never used one.
However, I have researched and have found the following information:
Can you install Google Play apps on Amazon Fire tablet?
Amazon Fire Tablets restrict you to the Amazon Appstore, but they run Fire OS, a custom version of Android. That means you can install Google's Play Store to gain access to millions of Android apps and games, including Google apps like Gmail, Chrome, Google Maps, and more.

I hope this helps?
Thanks,
