Downloading com.neonbanking.app is providing HMS variant instead of GMS one

Description

Not sure if this is a bug or not and if this is the right place to report such a thing.

I downloaded the app com.neonbanking.app from the Aurora Store and received an Huawei Message Service Core version of the app.

When I download the APK directly from the PlayStore a different variant of the app is being distributed using GMS instead of HMS.

https://play.google.com/store/apps/details?id=com.neonbanking.app&hl=en&gl=US

Expected Behaviour

The version using GMS is installed.

Actual Behaviour

The version using HSM is installed.

Steps to Reproduce

1. Open Aurora Store

2. Search for neon and choose neon - your account app

3. Download and install it

4. When launching the app a popup will appear that HMS Core is needed with this version

Environment

• Device model & codename: Oneplus 7 Pro "guacamole"
• Android version: 11.0.0
• Aurora Store version: 4.0.4
• Installation method: session
• OS: LineageOS 18.1 microG

Additional context

I assume that there are different variants of the app. The main question here is why is the one with HMS Core being distributed. I'd assume that it should take the PlayStore variante and not the AppGallery one.
