remove this obsolete app from apps.nextcloud.com please

Hello,
would it be possible to follow instructions on:

https://nextcloudappstore.readthedocs.io/en/latest/restapi.html#delete-an-app

and remove your past app:

https://apps.nextcloud.com/apps/spreedme

and help through this to tidy up the Nextcloud App store (most importantly it clutters apps catalogue in every Nextcloud instance) a bit please?

Thanks and have a nice day
