The official Guacamole Client code uses this:
https://github.com/apache/guacamole-client/blob/78e0436dc202673686dc8a7741eca6cb21513d77/guacamole/src/main/frontend/src/app/client/types/ManagedClient.js#L720-L728
I'd highly suggest going through the Guacamole Client code, particularly
for the AngularJS front-end, to see how it is handled in there - this block
only takes care of letting the client know that a required instruction has
been sent and prompting the user - you have to go to a couple of other
places to see where the user is actually prompted and where those responses
are actually sent back to guacd.
And to answer your question, no, there is no need to disconnect and
reconnect - in the cases where guacd sends the "required" instruction, it
is usually because there is a call-back function from one of the supported
protocols being invoked that needs more information and is now waiting on
that information to be provided.
I know that's a very high-level answer - feel free to post back with more
specific/detailed questions.
