An investigation by The Markup found Meta’s pixel tracking students from kindergarten to college
"After signing into their ACT account, if a student accepted cookies on the following page, Facebook received details on almost everything they clicked on—including scrambled but identifiable data like their first and last name, and whether they’re registering for the ACT. The site even registered clicks about a student’s ethnicity and gender, and whether they planned to request college financial aid or needed accommodations for a disability"
I don't think so. AFAIK there is no native method to caption images in markdown, which is what this editor uses. People try to bring about this effect by italicising the part they would want as a caption right underneath the image. However, in your case, I see a [You've done well] banner underneath the image, which I assume is the caption you meant. Not sure how that happened but if that works, great!
