Most other UX out there allow you to just submit something you’ve uploaded with no additional input, so I find this one a bit confusing for users.
**
Scenario**
Let’s say the chat asks user to upload a document.
They upload and go to hit the send button.
And the send button doesn’t work.
Here’s the trick to make it work: the current setup requires them to also type something in the text box to submit.
Once the user figures this out it’s not an issue, but I find on first use people are clicking the submit button and having a moment of confusion/friction.
