Is there an URL to open the Gmail compose window with a specific message ID in full-screen (pop-out)

Question

I use the new Gmail API to create a draft for my user. The API response provides the newly created message ID.

I can then open the compose window with the URLhttps://mail.google.com/mail/#drafts?compose=[message-id]. However I would like to open a full-screen (popped-out) compose window. Is there an URL for that ? This URL must of course be parameterised with the message id.

To be more precise, this is what I get, and this is what I want.

Answer 1

Try this:

https://mail.google.com/mail?authuser=[e-mail]#all/{message_id}

Just replace {message_id} with the actual ID string.
