How to remove the unpublished apk from the Google play console account

Question

I am developing an Android application and in this application, I am using "In app billing" features.

I uploaded apk on the google console account and set the product id, price and other required things and saved all the data in the draft.(Application is still in draft mode). I did not publish my app yet.

After a few minutes, I realized that I uploaded old signed apk file and keystore of this apk has already lost.

Now I want to remove this old apk file and want to upload a new one in draft mode.

My problems are :

1. How to remove the old apk file from the google console account.(In Draft Mode)
2. How to upload the new signed apk file with new key store (As I have lost my old key store)

EDIT:

I want to publish the app with the same name and with same package name. I do not want to change my app name atleast.

Answer 1

This can now be done by going to Release management > Artifact library and deleting the APK.

Answer 2

You cannot delete the artifacts anymore.

Here's a part of my chat with Pete through the built-in help & support.

Pete: Thanks for waiting. You can't remove an apk that you've already served. Your next Production apk has to be version code 3 or higher.

Me: So I can't just delete the artifact of that build?

Pete: That's correct.

(P.S. He mentioned version code 3 because of my specific issue)
