This is not coding related please dont downvote. i have tried multiple ways to remove app from app store connect

this is kind of old app i didn’t even work on it. now management told me to delete the old app and need to upload new app with same name. but i couldn’t remove old app

so i have changed old app name so that i can use same name to new app but still new app not approving the name

for old app i have like this in developer account.. but there is no build for 1.4.3 and we dont have updated code also to upload.

so i have selected both live and ready to submit apps > app information > down that page remove app

but none of them removed. how to remove app from appstore connect
