Help Needed: My App Is Ready for Google Play, But the Play Billing Library Version Is Incorrect

I’m seeking assistance with an issue I’m facing while trying to publish my game app on Google Play. I developed the app using the Unreal Engine, and I’m currently at the stage of creating an internal test version. However, the Google Play Console is showing an error stating that my app is currently using the AIDL version of the Play Billing Library and needs to be updated to version 6.0.1 or higher.

I tried modifying the build.gradle file, but I found that whenever I package the game with Unreal Engine, that file gets reverted. What steps should I take to properly update the Play Billing Library to version 6.0.1?
