Hi @ciiay, we like to follow https://github.com/backstage/community-plugins/blob/87b63379d186f1b0b2c8a9c2158169c9357f89a6/docs/plugin-maintainers-guide.md#archiving-a-plugin

But we don't want deprecate the npm package now. But can you add the essential information about the last release to this two files:

1. https://github.com/redhat-developer/rhdh-plugins/blob/main/ARCHIVED_WORKSPACES.md
2. https://github.com/redhat-developer/rhdh-plugins/blob/main/.github/archived-plugins.json

@christoph-jerolimov if the workspace is added to https://github.com/redhat-developer/rhdh-plugins/blob/main/.github/archived-plugins.json, it will trigger the GitHub Action to automatically deprecate on npm, so we should hold off on doing this.

Perhaps we open a separate JIRA as a reminder to add the plugin to the list once we are ready for deprecation.

LGTM. Approving so that it can be merged once the merge conflicts are resolved and the plugin is added to https://github.com/redhat-developer/rhdh-plugins/blob/main/ARCHIVED_WORKSPACES.md 🙂

For future reference, there is a script that automates the archive process for you (see https://github.com/redhat-developer/rhdh-plugins/blob/main/CONTRIBUTING.md#archiving-a-plugin-or-workspace).
