How to update plugin

I published an XD plugin the other day.

And today, I tried to publish a new version because I added some features.

To update the plugin, I referred to the following page.
https://www.adobe.io/apis/experienceplatform/console/docs.html#!AdobeDocs/adobeio-console/master/plugin-update.md

However, the Public plugin name in the listing information showed an error message "A plugin already exists with this name. Please use a unique name.

I don’t know how to update it as per the instructions. How can I update the plugin?

best regards

I tried again today, and it’s fixed!
