Plugin maintainer transfer

What is the method to transfer maintenance for a plugin? I understand the GitHub code transfer process but how about in Obsidian Releases?

Create a PR to change the entry in the community-plugins.json file, make sure to keep the credit to the original author.
You will have to provide something that can prove that the original author is fine with the transfer, they can leave a comment on one of their issues or on the PR to the obsidian-releases repo.

They’d be transferring the code base as well, ideally, so we wouldn’t just be a fork. I believe I now understand the requirements.
