Keep working in the background and unblock yourself. You should be prepared to do it all by yourself and handle the scenario of rest of your collaborators shelving the paper. You should not be delegating to seniors, that never works. Ideally, I would list things that need to be done. I would have a group meeting and ask what people are excited to do and how I can help them in the parts they are not ready to pick up.
