Clear math input box on click

Questions
1

I had a pre-filled Math Input box using

initialLatex: “Solution”

When a student clicks on the box, I would like the text to clear so that they can enter in their answer without having to delete the “Solution” text. Is there a command to do this?

Thank you

None as far as I know. Could you include a Note component above that says “Enter your solution below”? That would leave the math input blank
