how to change name of app or delete it

Hi, i need to change the name of an app im testing because I named it what I want the final release to be and I cant archive the final project from the original test project.

So basically I just need to either delete the app from test flgiht or change its name.

iv already tried uploading it in a different name but it just makes a new app and the original one remains.

So far it doesnt seem possible to do either by myself right?

Thanks
