Thunkable to Android Studio and update app

He wanted to know if the following happened to any of them:
Create an application in Thunkable, I published it in the play store. But now create the same app from android studio and I want to upload it to the play store.

"

"
Do you have any idea if something can be done? or do I have to upload it back as if it were a new app?
