There is no work to port the extension since the new edge is based on chrome. All users on Windows/macOS (and Linux in the near future) are already able to install it from the chrome web store when prompted to enable downloads from the CWS. The extension submission process is detailed at https://docs.microsoft.com/en-us/microsoft-edge/extensions-chromium/publish/publish-extension

I should also note that Microsoft is not charging developers to publish on the addons store, unlike CWS.
