How might I go about adding a game to google play steam ect

I have been working on a game for mobile lately. I was wondering how I would put It up on more major marketplaces. The game in question is still in a beta stage but has come along nicely in my eyes. UNIVERSAL CROSSING - Flowlab Game Creator that is the link if you would like to play test it.

You would want to Export the game, and wait for it to finish, and then download it

You need to be indie to export a game.

Go with itch.io or newgrounds

use google play
search google developer , u need to pay one time tax and have unlimited games
I done this :https://play.google.com/store/apps/details?id=io.flowlab.SnowmanBob1904646

Ok I know about indie, more so how would I get it to google play, thanks for the answers
