after many months of work, I'm finally putting the finishing touches to my android game.
I should be be ready soon to show a beta version of it in an upcoming video game fair, before the official release on Google Play Store.
My question is: how can I let selected people download the temporary version of my android game, avoiding it to possibly reach the general audience before the official release?
For example, I may consider to let influencer or YouTubers install a version of my app without advertising, but I wouldn't want it to be potentially downloaded other android users.
Any help is appreciated, thanks
