A different approach - useful if you want to do this sort of thing in many places

This bit is done once

Promise.prototype.thenWait = function thenWait(time) {
    return this.then(result => new Promise(resolve => setTimeout(resolve, time, result)));
};

Then you can use it, like this usage for your example, anywhere

apiGetLoggedInUser.thenWait(3000).then(user => sendMessage(user.name));
