Ask ARA - Gesture introduction? (24hr) (Patreon)

Last time on Ask ARA: https://www.patreon.com/posts/ask-ara-guest-3-18719431

Practice with Vikna reveals only that ARA has no formalities currently loaded. Faced with a few options, and no time left, the question this time around is this:

What quick action, phrase or gesture should be performed when greeting such a superior?

This is an open-ended question to the comments. This post will be open for one day here, and then make a short poll tomorrow for another day in which you all can vote on the best answer.
