Adding Owner to Flathub App Github

I am a developer for an app that I got published through Flathub submission process. I know have admin privileges for the relevant repo.

I need to add the Owner of the app so that they can have access to the Flathub Dev Portal and can then Verify our domain name through the Portal.

So would I be able to invite/add them through the relevant Flathub Github app repo?
