Sometimes it’s just a dialog with a single “Ok” button, and they stare at me and ask “now what?”. Like, you literally have only one option, what do you think?
From my exp, it’s asking for validation that what’s happening is expected. Also, sometimes the next step is not to click OK as another process may need to happen first.
I’m all good with people asking questions like that. They don’t have any intuition about what you’re showing them, so they’re hesitant to make assumptions and that’s ok.
This reminds me! At work we often send emails to customers through our ticket system so they are recorded. A new guy got a pop-up asking if he wanted to send the email. He looks at me and says “What do I do?” I say “Well you have 2 options: Yes to send the email or Cancel.” He clicks Cancel and is then confused the email never sent. He quit a few days later which honestly was better for all of us.
