Add ability to schedule messages to be sent at a later time

Feature Request

I haven't seen any existing issues mentioning this, please feel free to close if it has already been addressed. An extremely useful feature in other texting apps is to schedule a message to be sent at a given time. The easiest place to add this would be the + button when you start typing a message and viewing your scheduled messages via the options dropdown in the top right.

This feature is supported on the Android app. Why is it not in the desktop one?
