Hey there @Basit-qc 👋
as per our contributing guidelines:

A goal of Open VSX is to have extension maintainers publish their extensions according to the documentation. The first step we recommend is to open an issue with the extension owner. If the extension owner is unresponsive for some time, this repo (publish-extensions) can be used as a temporary workaround to ensure the extension is published to Open VSX.

The above also includes owners, who should publish the extension from their respective repositories in lieu of this one, so that they own the publishing process from end to end and reduce the maintenance burden on this repository.

We also have a guide on doing this via GitHub actions, which you may find useful: https://github.com/EclipseFdn/publish-extensions/blob/master/docs/direct_publish_setup.md.

Let me know if you have any questions!
