How can I use "return receipt" (Message disposition notifications) in mu4e. For composing as well as receiving messages?

For composing I tried to add a "RRT" field in the header, but receiving this mail with thunderbird didn't result in a "return receipt" pop up.

Vice versa I don't know how to make mu4e ask me for Message disposition notification if I receive such an email with mu4e.

Have you tried C-c M-n while writing the message? This at least should cover part of the answer. Regarding the visibility of the return receipt pop-up in mu4e, according to this thread such functionality does not exist at the moment
