First time I use Expo (react native app) to deploy an app into Googgle play store. Expo Generates an aab -file that I can upload to the store. But it seems like it is not obfuscated. Reading through the Expo documents I don't get my head around how to define this in my build process.

If I understand documentation correctly it is in my eas.json file I should define this, or have I misunderstood?

But I don't know how the code should look like. Any suggestions for how?
