GitLab CI publish Android apps to the Google Play Store with GitLab and fastlane

Thank you for this wonderful gitlab CI/CD product … It is saves a lot of time in the development process.

Gitlab is integrating each build into AWS Device Farm for e2e testing.

The next step is to publish to the Google Play Store from Gitlab and I would like to follow this guide here to accomplish that:

The issue is that I do not have an Apple Computer to perform this step and fastlane only works on Apple.
Could you offer suggestions for instructions on using Macincloud or Remotemac.io or is it not possible ?

Thanks !
