Exactly. In addition, the "first things first, let's buckle those belts" lady tells us:
If you need anything, don't hesitate to ask. As always, we're here to make your flight great, because great is what we're going for.

So, we have:
- An instruction to ask if we need anything, and
- An icon indicating how to summon someone to ask
Based on the above, it seems reasonable to press the button if we need anything.
